DESCRIPTION
Active elements of master oscillator and amplifier are installed in one pump chamber and are pumped by a single flash lamp. The master oscillator is based on the time-proven ring cavity design ensuring excellent beam quality while the classical single-pass amplifier is supplemented with the optics compensating thermooptical aberrations.
Particularly due to this technical solution the LQ629 provides unique combination of parameters in a compact, reliable and inexpensive-in-operation design.
All the critical components of the laser are thermally stabilised which in combination with vibration-proof design ensures unsurpassed long-term stability of output radiation. The efficient thermostats used in the LQ629 ensure warm-up time of less than 10min.
To reduce your time expenses on routine service of the LQ629 we provided flash lamp life time of more than 50 million pulses and foreseen easy and quick procedure of its replacement.
It should be noted that the laser design allows to replace the flash lamp without removing the laser head upper cover. Such a design concept considerably reduces risks of the optical components contamination as well as increases operational reliability of the device.
Closed-loop water-to-air cooling system is integrated into a compact single-phase laser power supply which can be controlled both from PC and via the remote control unit.

HARMONIC GENERATORS
In the standard configuration the LQ629 laser has built-in SHG. Upon your request the SHG, THG, FHG and FiHG can be supplied as external stand-alone modules.

OPO
Upon your request the LQ629 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.
