Q2-1064 Serie

Q2-1064 - Serie, gütegeschalteter Nd:YAG Laser, Dioden-gepumpt

Q2   1064

Quantas Q2-1064 models set new standard in Q-switched laser market. Q2 series diode pumped, fully air‑cooled lasers are designed for applications that require high peak power. Robust, reliable design is what makes this series ideal tool for applications like Laser Induced Breakdown Spectroscopy (LIBS), LCD repair, laser ablation, remote sensing and more. Broad selection of models are available offering 70mJ@50Hz or 40mJ@100Hz pulse energies.

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. Wavelenght extensions into infrared range by use of OPO 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.
