The combination of high laser pulse energy, high PRR and excellent beam quality unattainable for most conventional models is the peculiarity of the LQ629 laser.
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.

In the standard configuration the LQ629 laser has built-in SHG, THG and FHG. However, upon your request the harmonic generators can be supplied as external stand-alone modules. FiHG is available only as an external unit.

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).
Optical Parametric Oscillator for Nd:YAG lasers
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.
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.
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.
Attenuator of high-power laser radiation
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 LQ629 in laboratory experiments, as a bonus you will get unsurpassed operational reliability and minimisation of accompanying expenses.
If you are attracted by the reliability of the LQ629 laser and you will use it for industrial or field applications, in addition to a highest reliability you get beam quality conventionally available only for high-precision laboratory equipment.
The LQ629 is an ideal instrument for such applications as:
