Problems solved by technology

[0003] The resonators in today's LD-pumped solid-state lasers are all flat-concave cavity structures. Since only one point on the concave mirror of the resonator with this structure resonates with the plane mirror, the adjustment process is time-consuming and laborious, and most of them are manually adjusted. The adjustment of crystals and optical components increases the workload and complexity of the modulation process, affects the adjustment rate, and is prone to precision errors, resulting in unsatisfactory output laser quality and low production efficiency, so it is difficult to achieve mass production

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] figure 1 It is a structural schematic diagram of the patch type solid-state laser described in the present invention.

[0027] like figure 1 As shown, the patch-type solid-state laser includes an LD pumping light source 101 and a resonant cavity, and the LD pumping light source 101 is a fiber shaped and compressed LD pumping light source for providing pumping light. The resonant cavity includes a laser crystal 102 and a frequency doubling crystal 103 parallel to each other. The laser crystal 102 is used as a working material of the laser to convert the pumping light provided by the LD pumping light source 101 into fundamental frequency light. In the present embodiment, laser crystal 102 selects Nd:YVO 4 (Nd-doped yttrium vanadate) crystal. The frequency doubling crystal 103 is used to convert the fundamental frequency light emitted b...

Abstract

The invention discloses a surface mount device (SMD) solid laser which comprises an LD (laser diode) pumping light source and a resonant cavity, wherein the LD pumping light source is formed by optical fiber shaping and compression; the resonant cavity comprises a laser crystal and a frequency doubling crystal which are parallel to each other; and the LD pumping light source, the laser crystal and the frequency doubling crystal are fixed on the same laser substrate. At the same time, the invention also discloses a manufacturing method of the SMD solid laser. The manual adjustment process in the traditional resonant cavity modulation method is omitted, the errors caused by manual operation are avoided and the production efficiency is improved through the methods of pre-marking and fine grinding and polishing after pre-sticking.

Description

technical field [0001] The invention relates to the field of solid-state lasers, in particular to a patch-type solid-state laser. At the same time, the invention also discloses a manufacturing method of a patch type solid-state laser. Background technique [0002] With the increasing development and maturity of semiconductor technology, laser diodes (Laser Diode, LD for short) have been greatly improved in terms of power, conversion efficiency, wavelength extension and operating life. LD has the characteristics of high quantum efficiency, high reliability, long service life, easy correspondence between emission wavelength and absorption peak of laser medium, and good quality of laser output beam. This makes the combination of LD and pumping technology, resulting in LD-pumped solid-state lasers. It has the advantages of high efficiency, high beam quality, long life, full curing, compact structure and light weight, so it has attracted more and more attention. It has a wide ...
