Choosing an InnoLas Laser by Energy and Repetition Rate

InnoLas Laser builds pulsed solid-state Nd:YAG lasers with flashlamp and diode pumping. The flashlamp-pumped SpitLight Compact delivers 100-400 mJ, SpitLight 400, 600 and 1000.1 deliver 400-1000 mJ, and the high energy SpitLight 4000 and 7000 exceed 4000 and 7000 mJ at 5-10 Hz.

The diode-pumped DPSS 250 runs at up to 1000 Hz, and the EVO series scales from EVO I to EVO IV with up to 300 W average power. Double rail lasers serve PIV, tunable OPOs serve spectroscopy, and Picolo and MAGNA deliver sub-nanosecond pulses.

Flashlamp or Diode Pumping

Flashlamp pumping gives high pulse energy at moderate repetition rates: SpitLight 400-7000, PIV and OPO at up to 30 Hz. Flashlamps are changed quickly, with a lamp lifetime of more than 40,000,000 shots stated by the manufacturer.

Diode pumping in the DPSS 250, EVO and MAGNA EVO is designed for 100 Hz to 1 kHz, and the pumping chamber is maintenance-free. Harmonic modules provide 532, 355, 266 and 213 nm, and injection seeding provides single longitudinal mode operation.

Applications: Spectroscopy, LIDAR, PIV, Photoacoustics

According to the manufacturer, InnoLas lasers are used in spectroscopy (LIF, LIBS, MALDI, CARS, Raman), LIDAR, PIV, PTV and LDV flow measurement, high energy physics and Thomson scattering, and photoacoustic tomography, microscopy and endoscopy.

Industrial uses include laser peening, laser ultrasonic testing and annealing, defect inspection and display repair, and laser induced damage threshold (LIDT) testing of optics.
