HIGH-POWER PULSED ND:YAG LASERS
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
APPLICATIONS
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)
Ablation
Plastic and Ceramic Components Marking
Laser Cleaning
DESCRIPTION
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.
Typical beam profile at 1064 nm. Near field
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 LQ929 ensure warm-up time of less than 10 min.
To reduce your time expenses on routine service of the LQ929 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.
