Quantum Light Instruments Ltd. innovative water-free laser crystal cooling technology enables generation of high quality laser beam with up to 100 mJ pulse energy and/or up to 4 W average output power. Q2HE series sets new standard in Q-switched laser market. Advanced laser design resulted in compact, user-friendly turnkey system that requires little maintenance. There is no chillers or bulky power supplies that one needs fit under the table. Most of laser electronics is integrated into housing of the Q2HE and the only external modules are compact controller box and mains adapter that provides 27 VDC, 50-150 W power (depending on model). Less than 7 ns pulse duration and low divergence of the beam enables efficient fundamental wavelength conversion to higher harmonics with shortest wavelength available of 211 nm. Low jitter triggering pulses for user equipment are available in internal triggering mode. If required, laser pulsing can be externally triggered from delay generator. Laser is controlled trough Ethernet port via build-in web-server. There is no need to install control software – any computer or even cell phone with modern web-browser installed will be able to control Q2HE. API is provided for integration with user devices.
