Problems solved by technology

In addition, the thermal shock resistance of alumina is poor, and there is a large temperature rise in a very short period of time during the surface discharge process, resulting in overall cracking of some alumina substrates after several or dozens of discharges
[0006] Currently, limited by the anti-ablation performance of the surface discharge substrate, the operating life of the surface discharge optical pump source is short, which limits the application of high-power repetition frequency XeF(C-A) blue-green lasers in the underwater laser field.

Abstract

The invention discloses a surface discharge type glass substrate for a light pumping source. The surface discharge glass substrate comprises a quartz glass body and a diamond ablation-resisting coating deposited on the quartz glass body, wherein the diamond ablation-resisting coating is only deposited on the surface of the quartz glass body, so that a surface discharge region is generated. The preparation method provided by the invention comprises the following steps: preparing a diamond-powder-containing turbid liquid; grinding the surface of the quartz glass body by using the turbid liquid, and then performing ultrasonic oscillating pretreatment; shielding a region, in which surface discharge is not generated, on the quartz glass body; and forming the diamond ablation-resisting coating on the surface of the quartz glass body by performing hot filament chemical vapor deposition to obtain the surface discharge type glass substrate. The surface discharge type glass substrate provided by the invention has the advantages of plasma ablation resistance, high reusing time, low cost and the like.
