Q2-1053 Serie

Q2-1053 - Serie, gütegeschalteter Nd:YLF Laser, Dioden-gepumpt

Q2   1053

Quantas Q2-1053 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@10Hz or 100mJ@20Hz 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. Two models are available offering 70 mJ @ 10 Hz or 100 mJ @ 20 Hz pulse energies. Less than 10 ns pulse duration allows efficient fundamental wavelength conversion to higher harmonics with shortest wavelength available of 211 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 450 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.
