Abstract

Wave-guide laser working medium with certain width is divided into three pieces along longitudinal direction. Then, after roughing side face of the divided pieces, they are assembled. The said wave-guide laser working medium is composed of Nd:YAG wve-guide working medium and bound edge at two surfaces. Nd:YAG wave-guide working medium is YAG crystal with Nd in ion concentration 1.1% being adulterated. Bound edge is YAG crystal without Nd being adulterated. The invention restrains parasitic oscillation effectively and outputs double laser output power.

Description

Technical field:

[0001] The invention relates to a high-efficiency waveguide laser, in particular to a method for suppressing the parasitic oscillation of the waveguide laser. Background technique:

[0002] In recent years, waveguide lasers have been developed rapidly. The biggest advantage of this type of laser is that it adopts diode pumping, which not only has a compact structure, but also has high light-to-light conversion efficiency, and can operate in a single mode in a continuous or pulsed state. Diode-pumped Nd:YAG lasers have been widely used in many fields such as industry, telecommunication, and military industry.

[0003] In order to increase the continuous output power of the diode-pumped single-mode waveguide laser to the kilowatt level, various effective technical measures have been taken, such as using various coupling methods to efficiently couple the diode-pumped light In the waveguide, various unstable cavity control modes are used to control the operatin...
