The Radiant QX4130 from OPOTEK is a Tunable Laser Module that operates from 410 to 2500 nm. It provides a pulse energy of 450 mJ @ 450 nm with a repetition rate of 20 Hz and has a pulse width from 4 to 7 ns. The laser produces a beam with a diameter of 6.5 mm and a divergence of less than 1.5 mrad. It utilizes optical parametric oscillator technology to generate wavelengths over a broad range in the UV, VIS, and IR spectrum. The wavelength tuning is motorized and computer-controlled. The laser is available in a module that measures 29 x 16 x 10 cm.
