Abstract

The invention relates to an all-solid-state neodymium-doped potassium-gadolinium tungstate laser experimental system, which relates to teaching experiments and scientific researches, and is particularly suitable for the studies and the researches on the principles and the characteristics of laser by teachers and students of photo-electricity profession in various universities and colleges. The laser experimental system consists of a laser power supply, an LD laser, an Nd: KGd(WO4)2 laser crystal, a KTP frequency doubling crystal, a passive Q-switching crystal, a laser output mirror, a picosecond grade photodiode, a red laser aligner, an optical track, a sliding seat, an optical bench, a mirror holder, a safe interlocking switch, a special connecting cable and a dustproof protecting cover. With the application of the all-solid-state neodymium-doped potassium-gadolinium tungstate laser experimental system, the national optics educational standard can be improved, the innovation ability and the research and development thinking of students can be cultivated, the development progress of the prior solid-state laser can be known, and the latest laser techniques of the prior world can be mastered.

Description

technical field [0001] The invention relates to teaching experiment and scientific research, and is especially suitable for teachers and students majoring in optoelectronics in universities and colleges to learn and research laser principles and characteristics. Background technique [0002] Laser experiments play an extremely important role in the development and teaching of laser science. Theory and experiment are interdependent and promote each other. Many laser principles and theorems are summarized through experiments or verification. [0003] At present, in the field of laser teaching, there is usually a boring and rigid pure theoretical education method. Even if there is a laser experiment instrument, it is bulky and can do a single experiment. It is not suitable for teaching laboratories, so it is difficult to achieve the theory and experiment. Combined, the teaching is lively, interesting and effective. It is difficult to stimulate students' innovative ability and ...
