The STLQ830 is a new model of lamp-pumped Nd:YAG laser possessing unique laser radiation characteristics: linewidth of less than 0.1 cm-1, low angular divergence of less than 0.25 mrad and high pulse energy up to 700 mJ at 1064 nm.

Master oscillator with high-stability ring cavity, preamplifier and high-power amplifier form at the laser output TEM00 diffractionally limited beam with high pulse energy and Gaussian profile in the far field.

High spectral radiation brightness with linewidth not more than 10pm and high coherence length of more than 10 cm is ensured by intracavity Fabry-Perot interferometer.

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 STLQ830 ensure warm-up time of less than 10 min.

To reduce your time expenses on routine service of the StLQ830 we provided flash lamp life time of more than 30 million pulses and foreseen easy and quick procedure of its replacement.

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.

High-Power Pulsed Nd:YAG Lasers Model STLQ929

Up to 1400mJ @ 1064nm and harmonic generators up to 213nm

FEATURES:
 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

The STLQ929 is a series of compact lamp-pumped Nd:YAG lasers built under the scheme masteroscillator – 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.

The master oscillator of the STLQ929 laser series, just as that of the STLQ529 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.

To reduce your time expenses on routine service of the STLQ929 we provided flash lamp life time of more than 30 million pulses and foreseen easy and quick procedure of its replacement.

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.
