Model LQ929
FEATURES
The LQ929 is a series of compact lamp-pumped Nd:YAG lasers built under the scheme master-oscillator – one-pass amplifier and having uncompromising combination of the main parameters: high output power, exceptional beam quality and minimum laser head and power supply dimensions.
OSCILLATOR-AMPLIFIER CONFIGURATION
HIGH PULSE ENERGY UP TO 1.5 J
EXCELLENT BEAM QUALITY
ALL THE HARMONICS AVAILABLE UP TO 213 NM
COMPACT SINGLE-PHASE POWER SUPPLY
NO EXTERNAL WATER REQUIREMENTS
DESCRIPTION
Typical beam profile at 1064 nm. Near field
The master oscillator of the LQ929 laser series, just as that of the LQ529 has ring cavity. The principle of operation of the ring cavity scheme and utilisation of pump chambers with high-efficiency diffuse reflectors provide output laser radiation with homogeneous beam profile and exceptional stability of output energy and spatial radiation parameters.

HARMONIC GENERATORS
In the standard configuration the LQ929 laser has built-in SHG. Upon your request the SHG, THG, FHG and FiHG can be supplied as external stand-alone modules.
LG101 & LG103 External generators for Nd:YAG lasers
OPO
Upon your request the LQ929 laser can be supplemented with an optical parametric oscillator of the LP600 series. In such a combination you will have a source of continuously tuneable laser radiation within a wide spectral range (from UV to IR).

THE LZ221 RAMAN SHIFTER
Compact and easy to adjust and operate Raman shifter efficiently converts 1064 nm or 532 nm output radiation into several additional laser lines within the visible and IR range.
IR CONVERTERS
The IR converters are very compact devices with built-in OPO operating in the NCPM mode. The range of IR converters are laser sources providing fixed output wavelengths from 1.5 µm to 3.5 µm.
POWER ATTENUATOR
The laser can be supplemented with a variable power attenuator. Upon your choice it can be either a unit optimised for operation at one wavelength or an achromatic attenuator intended for simultaneous attenuation of all the laser harmonics from 266 nm to 1064 nm.

ARTICULATED ARM
A number of applications require quick and flexible laser beam delivery to the research object or the place of measurements. For this an optical fiber can be used but only for delivery of low pulse energy radiation (5-20 mJ). To deliver high-power radiation we offer to supplement the laser with a mirror articulated arm. To minimise losses of laser pulse energy we use special dielectric mirrors with high reflection coefficient simultaneously for 1064 nm and 532 nm.

If you plan to use the LQ929 laser in laboratory experiments, as a bonus you will get unsurpassed operational reliability and minimisation of accompanying expenses.
The LQ929 is an ideal instrument for such applications as:
Ti-Sapphire and OPO Pumping
Dye Lasers Pumping
Spectroscopy
LIDAR
LIF (Laser Induced Fluorescence)
LIBS (Laser Induced Breakdown Spectroscopy)
Education
PIV (Particle Image Velocimetry)
