New TECHNOLOGY-series lasers for OEM

 

TECH-series datasheet

Laser-compact group introduces a new series of unique actively q-switched DPSS lasers which is intended to be used in industrial applications. Development of this series (brand name -"TECHNOLOGY") is based on many years experience in R&D and manufacturing of Q-switched lasers: more than 2,500 of this kind lasers (mainly UV) have been produced for OEMs in mass-spectrometry, micro-dissection and marking applications.

Small and powerful TECHNOLOGY-series lasers are new alternatives to the large, complicated and expensive high-power lasers. Due to combination of high pulse energy and peak power, ultra-compact footprint and conductive cooled laser head, superior pulse-to-pulse stability and beam quality, low power consumption and maintenance-free operation, they meet OEM customers' requirements and are more adequate for commercial applications.
Offering both high power and high laser intensity on target (GW/cm2) in the visible and UV, these lasers present unique advantages for efficient laser micromachining (especially of transparent materials).


TECH-series include four different lines: Express, Specific, Basic and Advanced. Each line has its advantages.

Express line features the shortest pulse width and provides the highest peak power: up to 300 kW at 1053 nm and up to 250 kW at 527 nm.

Specific line offers the smallest high-energy lasers for OPO pumping and other applications. It features longer pulse width compared with the other lines and the highest pulse energy: up to 2 mJ in IR and up to 1 mJ in green spectrum range.

Basic line of TECHNOLOGY-series lasers with low power consumption and economic price was specially designed for budget applications. Advanced line features the highest average output power (at 4 kHz) and higher pulse energy compared with Basic line models. 263, 351, 527 and 1053 nm wavelengths are available.

If required to use different wavelengths in conditions of funding shortage, it is possible to purchase several laser heads with one power supply (for alternate operation).

TECH-series lasers are ideal sources for use in micro processing of different materials, including biological tissues, thin films, multilayered structures and semiconductors (for example, resistors trimming, LCD repair, scribing of photovoltaic and other electric thin films, marking of cables, PC boards, gemstones, surface or inside-glass marking, etc.)

We inform our customers that the YLF-line of the DTL-series pulsed lasers (models DTL-394QT, DTL-399QT, DTL-392QT, DTL-389QT, DTL-379QT, DTL-419QT, DTL-319QT, DTL-429QT and DTL-329QT) will be discontinued till the end of 2014! We will not accept Purchase Orders for these models in 2015!!!

As replacement, we offer modern 'TECHNOLOGY' series lasers which feature improved laser parameters and reliability. Basic line provides the closest specifications to discontinued YLF-line lasers. Popular multi-wavelength lasers with output at 3 wavelengths will be available in TECH-series design as well.

MULTIWAVELENGTH LASERS


We offer several models of multiwavelength Q-switched lasers with simultaneous pulses at different wavelengths. Models DTL-399QT and DTL-394QT with output at three wavelengths in IR, visible (green) and UV spectrum ranges are available. The lasers emit simultaneous pulses at 1053, 527 & 351nm (DTL-399QT) or at 1053, 527 & 263 nm (DTL-394QT) in one beam with the same direction. Additional advantages are possibility to separate the required wavelength with external optics and numerous usage modes. The multiwavelength lasers are cost effective solutions for many scientific applications. DTL-392QT model with simultaneous radiation at two wavelengths (1053 & 527nm) is also available.

Applications: various types of spectroscopy, light detection (aerosol and fluorescence measurement and detection), hi-tech R&D, photoacoustics (laser-based ultrasound for non-destructive inspection of materials), laser microscopy.

 

ULTRAVIOLET LASERS


We offer several models of actively Q-switched short-pulsed UV lasers with output at 263nm, 351nm and 355nm. Over the past few years ultraviolet lasers are the most popular products from Laser-compact's product range.

Due to long-term cooperating with OEM customers, we have good experience in R&D and manufacturing of reliable UV lasers for mass-spectrometry, laser microdissection, marking and environment monitoring projects, where our UV lasers are used. The main advantage of our Q-switched UV lasers (as example, compared with Nitrogen lasers) is long-term maintenance-free operation, which enables their use in analytical and industrial equipment.

Applications: mass-spectrometry (MALDI TOF), laser microdissection, laser-induced fluorescence, marking, biotechnology, high technologies R&D, environment monitoring.

 

GREEN LASERS


We offer a wide variety of pulsed and CW lasers with radiation in green spectrum range.

Our pulsed green lasers are actively Q-switched. We offer DTL-series lasers (DTL-419QT and DTL-314QT) with pulse energy up to 200 at 527 nm and TECH-series lasers with pulse energy up to 1000 at 527 nm. The lasers feature short pulse width of less than 7 ns, high stability of laser pulse energy, possibility of external and internal triggering, PC control and a wide range of pulse repetition rates (from single pulses to more than 10 kHz). The applications of our green pulsed lasers include marking, micro-machining and testing of materials, photoacoustics and remote sensing.

Continuous Wave single-frequency green lasers are presented with S-series modules and complete laser system SLM-417. The most important applications are: Raman spectroscopy, laser microscopy, interference measurements, spectral analysis, flow cytometry, holography, laser-assisted measurements. Green low noise S-series laser modules LCM-S-111 feature a single longitudinal mode, low optical noise (0.2 % RMS or 0.9% peak-to-peak), high coherence length and narrow line width (0.00001 nm). They provide stable output power in a wide operating temperature range due to MCU based driver with two-channel TE-controller. S-series laser modules are small-size OEM units intended for the custom equipment in various OEM projects. High repeatability of parameters from sample to sample allows prompt alignment during assembly and maintenance. Different beam parameters are available as option. Modification LCM-S-111-20-R has been specially developed for Raman spectroscopy. Due to a special technical solution, back reflection hitting output laser aperture does not have an essential influence on the output power stability and the level of optical noise. This advantage makes the laser an ideal source for use in Raman spectroscopy.

The model SLM-417 is a single-frequency complete laser system with output at 532 nm compliant with FDA 21 CFR 1040.10 and 1040.11 for complete laser products. It features a single longitudinal mode, low noise, high coherence length, narrow linewidth and stable output power in a wide operating temperature range. The special feature of the SLM-417 is manual output power adjustment. The laser has compact size and is available in powers 20 or 50 mW.

T-series laser modules designed for OEM applications radiate up to 20 mW at 532 nm. They feature stable output power within wide temperature range and life time of 10,000 hrs verified with real-time tests. T-series module incorporates a driving electronics. Therefore, no additional driver for the laser diode is required. In order to operate, the module just needs a 3.3 VDC power supply. Each LCM-T-series laser module features an active power stabilization control loop. This control loop monitors output radiation of the laser module and maintains it at constant level within a wide temperature range. Spherical-mirror laser cavity provides perfect and stable beam geometry. Two-lens output optics yields well collimated centered and aligned beam. The above features allow considering T-series laser modules as the best price-performance choice for many practical applications.

Besides, we offer the modification LCM-T-111-AP with analogue power adjustment and possibility of TTL modulation.

Small T-series laser modules are used for positioning and projection in medical and industrial equipment, for alignment in optical systems. They became popular models among our customers due to high quality, reliable long-term operation ( 10,000 hours lifetime) and easy installation and use. Despite competition from cheaper red semiconductor lasers, green laser modules remain attractive for customers due to soothing green color (which is particularly important for medical equipment) and high brightness at a safe level of output power.

 

INFRARED LASERS


The simplest and most reliable of our lasers are infrared lasers. This applies both pulsed and continuous wave models. For many years our customers have confirmed long-term and stable operation of our IR lasers.
