LEOI-50 is designed for nonlinear optical experiments of laser teaching at universities/colleges. It can help students to understand the theory of diode pump solid state laser (DPSS) and frequency doubling.
A solid state laser with Nd: YVO4 as the laser material and pumped by a semiconductor laser at 808nm, emits infrared light at 1.064μm.
By putting a KTP crystal into the cavity to generate frequency-double green light, it is possible to observe frequency doubling phenomenon, and measure frequency doubling efficiency, phase matching angle and other basic parameters.
During the experiment, a lot of light path adjustment is involved, allowing students to acquire more familiarity on the principle practically.
