Quantas Q2 models set new standard in Q-switched laser market. Q2 series diode pumped, fully air-cooled, Q-switched lasers are designed for wide range of applications that require high peak power pulses. Robust, reliable design is what makes this series ideal tool for applications like Light Induced Breakdown Spectroscopy (LIBS), LCD repair, laser ablation, remote sensing and many others. Broad selection of models are available offering 70 mJ @ 50 Hz or 40 mJ @ 100 Hz pulse energies. Less than 10 ns pulse duration allows efficient fundamental wavelength conversion to higher harmonics with shortest wavelength available of 213 nm. Wavelength extensions into infrared by use of OPO range are available by request.
TEC based cooling eliminate risks associated with water cooling (like leaks, circuit shortening etc.) as well as reduce running cost due to no maintenance required.
Low jitter triggering pulses for user equipment are available with up to 300 µs lead in internal triggering mode. If required, laser pulsing can be externally triggered from delay generator.
Laser controlled via built-in Ethernet port trough web-server with option to add Wi-Fi adapter. It allows users to monitor and control laser remotely.
