LPT-7 Diode-Pumped Solid-State Laser Demonstrator

Short Description:

LPT-7 is designed for nonlinear optical experiment teaching in Colleges and universities. It can help students understand a diode pumped solid-state (DPSS) theory and laser frequency doubling technology. A solid-state laser: YVO4 crystal as gain material, which is composed of semiconductor laser pumping wavelength of 808 nm and emission at 1.064 M. infrared light through the KTP crystal as laser intracavity frequency doubling green generation, it is possible to observe the phenomenon and the measurement frequency, the frequency doubling efficiency, phase angle and other basic parameters.
