Q-Spark - Serie, gütegeschalteter Nd:YAG Laser, Dioden-gepumpt

Q Spark

Q-SPARK air-cooled, Q-switched, diode pumped lasers are designed for applications that require high peak power. Due to short laser cavity and good thermal properties laser delivers up to 10 mJ at < 2 ns and repetition rates up to 50 Hz. This laser is an ideal and robust tool for applications like Laser Induced Breakdown Spectroscopy (LIBS), remote sensing, Light detection and ranging (LIDAR), semiconductor failure analysis or laser ablation

Q-SPARK diode pumped, air-cooled, Q-switched lasers are designed for wide range of applications that require high peak power pulses. Due to short laser cavity and good thermal properties of Nd:YAG crystal laser delivers up to 10 mJ at < 2 ns pulse length. Pulse repetition rates up to 50 Hz is possible. This laser is ideal and robust tool for applications like Light Induced Breakdown Spectroscopy (LIBS), remote sensing, LIDAR, semiconductor failure analysis, laser ablation and many others. Short pulse duration allows efficient fundamental wavelength conversion to higher harmonics with shortest wavelength available of 266 nm. 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 with option to add Wi-Fi adapter. It allows users to monitor and control laser remotely.
