Diode Pumped Nd: Yag Laser with Frequency Doubling

Properties of diode laser Nd:YAG crystal Optical pumping Rate Equation Model Static and dynamic solution Laser output power Laser resonator Transversal modes Cavity stability criterion Spiking Nd:YAG laser Nonlinear optics Phase matching condition Conversion efficiency Verification of quadratically relationship SHG power Clear demonstration of transverse modes Intra cavity iris for TEMoo operation
Principle of operation Inside the cavity formed by the mirror (M1) and (M2) a KTP crystal is placed. The fundamental radiation is frequency doubled generating visible green radiation at the wavelength of 532 nm. The filter (F) blocks the pump as well as fundamental radiation in such a way that only green radiation can be characterised.
