P5.8.6.3 Diode Pumped Nd: Yag Laser with Frequency Doubling

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.   1 - 474 1031 Module B - Collimating optics on carrier MG-65 with Melles Griot 1 - 474 104 Focussing Optics, f = 60 mm 1 - 474 109 KTP Crystal with Adjustment Holder 1 - 474 5310 Crystal in holder Nd:YAG 1064 nm 1 - 474 5311 Laser mirror in holder SHG 100 1 - 474 113 Laser Mirror Adjustment Holder, left 1 - 474 114 Laser Mirror Adjustment Holder, right 1 - 474 5453 Crossed Hair Target in C25 mount 1 - 474 107 Filter Plate Holder 1 - 468 74 Filter, infrared 1 - 468 77 Light filter, green 1 - 474 4025 IR converter screen 0.8 - 1.6 µm 1 - 474 306 Photodetector signal conditioning box 1 - 474 108 SiPIN photodetector 1 - 474 5464 Oscilloscope, Dual Channel, Digital 1 - 501 06 HF-Cable, BNC-BNC, 1.5 m 1 - 501 061 HF-Cable, BNC-Mini BNC, 1.5 m 1 - 474 302 Controller for Diode Laser 1 - 474 102 Diode Laser Head with Adjustment Holder 1 - 474 5442 Profile rail, 500 mm 1 - 474 122 Optics cleaning set 1 - 671 9700 Ethanol, absolute, 250 ml 1 - 474 251 Transport and Storage Box #01 1 - 474 7106 Manual DPSSL 1 - 474 137 * Spatial filter with adjustable iris Articles marked with * are not essential, we do however recommend them to carry out the experiment.
