Abstract

The embodiment of the invention discloses a laser diode area array pumped uniformity detection apparatus. The apparatus comprises a laser diode area array; an optical waveguide for performing uniformization on pumped light emitted by the laser diode area array; a V-shaped reflector panel for reflecting the pumped light emitted by the optical waveguide towards the two sides of the optical waveguide; a laser transmission fiber including a fiber joint and a fiber tail end, wherein the fiber joint is fixed on the V-shaped reflector plate for receiving the pumped light emitted by the optical waveguide; a driver for driving the V-shaped reflector panel to move relative to the light-emitting surface of the optical waveguide according to a predetermined mode; a power meter probe disposed at the backlight side of the V-shaped reflector plate for detecting the optical power value of light emitted by the fiber tail end; and a processor for receiving the optical power value and analyzing the optical power value according to the predetermined mode so as to obtain uniformity distribution. According to the embodiment of the invention, quantification processing can be performed on the uniformity distribution of a certain light receiving area, and the laser diode area array pumped uniformity detection apparatus has the advantage of quite high detection accuracy.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a laser diode area pump uniformity detection device. Background technique [0002] Solid-state lasers pumped by semiconductors have been widely used due to their advantages such as small thermal effect, good stability, and compact structure. In the 1980s, with the development of semiconductor laser technology, the performance of a single laser diode has been greatly improved, especially the rapid development of semiconductor arrays, making solid-state lasers full of vitality. [0003] Whether it is for the traditional rod-shaped laser working medium or the slab-shaped laser working medium, in order to obtain high-power and high-beam-quality laser output, a high-power and high-performance pump source becomes an ideal pumping source. structure, and the semiconductor array just meets our needs. Not only that, in order to obtain laser output with high beam quality, we not only need ...
