Pulsed Lasers at 532 nm for LIBS, Marking, Lidar and Photoacoustics

HÜBNER Photonics introduced a new wavelength in the Cobolt Tor Series of a high-performance, compact, air-cooled, Q-switched lasers. The Cobolt Tor XE 532 nm delivers 0.25 mJ per pulse at up to 1 kHz repetition rate in a compact laser head which contains all drive electronics. The Cobolt Tor XE is intended for integration into instruments for marking, laser induced breakdown spectroscopy (LIBS), lidar as well as photoacoustic microscopy applications.

Using the sophisticated laser cavity design characteristic to the Cobolt Tor Series, the Cobolt Tor XE 532 nm delivers a unique combination of compact size and performance: kHz repetition rates, short pulse lengths (1-3 ns) and excellent pulse-to-pulse stability (jitter < 2 us) for a passively Q-switched laser in a TEM₀₀ beam. In addition, through advanced and fully integrated control electronics the emission can be triggered from single pulses up to 1 kHz pulse trains or bursts of pulses using external or internal trigger signals, or a combination of both.

The lasers are manufactured using proprietary HTCure technology in a compact and hermetically sealed package, which provides a very high level of immunity to varying environmental conditions and exceptional reliability. Lasers built using the HTCure technology have shown to withstand multiple 60 G mechanical shocks in operation without any sign of degraded performance. They can be exposed to extreme temperatures (>100 °C) and are insensitive to pressure and humidity.
