Microchannel module in laser

Abstract

The present invention relates to a micro passage module in laser, which comprises three support units, a module body, a water cooling system, a flange plate shaft joint, a front end piece, a LD electrode and a YAG rod. Three support units are respectively arranged on the module body in parallel, and nine diode modules constitute a series circuit and educe a pair of anode cathode LD electrode post heads. The module body is fixed with the front and rear flange plate shaft joints. The rear flange plate shaft joint is fixed with a rear pressing plate and the front end piece is fixed with the front flange plate shaft joint. A water stream pipe is arranged and sealed in the middle of the module body. The YAG rod is arranged and sealed in the water stream pipe. The YAG rod is fixed by the front and rear pressing plates. The water stream pipe is fixed by the front and rear flange plate shaft joints. The module body has two sets of water cooling systems. Two holes on the side face of the module body are communicated with the inlet and outlet of the water cooling system of the support unit. Two ends of the module body are communicated with the water stream pipe. The present invention has the advantages of high electro-optic transfer efficiency, reliable performance, long life-span and good quality of output beams.

Description

technical field [0001] The invention relates to the technical field of micro-channel modules used in lasers, in particular to a micro-channel module in a laser with high conversion efficiency, reliable performance, long service life and good output beam quality. Background technique [0002] In recent years, the domestic laser industry is developing rapidly, especially in the field of medium and small power laser processing equipment, and the competition is fierce. This requires us to have the technology of independent innovation intellectual property rights in order to have the ability to occupy the market. In the past, the commonly used solid-state lasers on the market were lamp-pumped lasers, and the pump lamp was a broadband pump. Only a very small part of the radiation spectrum of the lamp was absorbed by the crystal rod and converted into laser energy, and the conversion efficiency was only 3% to 6%; The radiation spectrum of the diode module in the diode laser basica...

AI Technical Summary

Problems solved by technology

In terms of performance and life, the life of the pump lamp is about 300 to 1000 hours. Changing the lamp will interrupt the work of the system and reduce the efficiency of the automatic production line; while the diode module has reliable performance and its life is much longer than that of the pump lamp, reaching 15,000 hours.
