Problems solved by technology

Due to the large divergence angle of the laser light-emitting chip on the fast axis, in order to effectively ensure the luminous quality of the semiconductor laser, it is necessary to use the fast-axis lens to collimate the light beam emitted by the light-emitting chip on the fast axis. The existing fast-axis collimation process is generally It is done manually, which leads to problems such as low accuracy and low efficiency of collimation

Abstract

The invention discloses semiconductor laser fast-axis collimation equipment used for adjusting the position and angle of a fast-axis lens so as to perform fast-axis collimation on light beams emittedfrom a semiconductor laser light emitting chip. The semiconductor laser fast-axis collimation equipment comprises a substrate, a chip bearing frame mounted on the substrate, an adjustment fame mountedon the substrate, a lens clamp mounted on the adjustment frame, an image collection assembly mounted on the substrate, and an optical detection assembly mounted on the substrate; the image collectionassembly is used for identifying the position of the fast-axis lens through image detection; and the adjustment frame is used for adjusting the position and the angle of the lens clamp to enable thelaser light beams to form light spots on the optical detection assembly. The semiconductor laser fast-axis collimation equipment, by virtue of detection and analysis of the image detection assembly orthe optical detection assembly, controls the action of the adjustment frame, so that automation of the semiconductor laser fast-axis collimation can be realized, frequent manual operation is avoided,and production efficiency of the semiconductor laser is improved.

Description

technical field [0001] The invention relates to laser adjustment technology, in particular to a semiconductor laser fast axis collimation device. Background technique [0002] The beam emitted by the light-emitting chip in the semiconductor laser is a divergent elliptical beam. The direction parallel to the light-emitting surface is the slow axis, and the divergence angle is about 10°. The direction perpendicular to the light-emitting surface is the fast axis direction, and the divergence angle can reach 40°. . Due to the large divergence angle of the laser light-emitting chip on the fast axis, in order to effectively ensure the luminous quality of the semiconductor laser, it is necessary to use the fast-axis lens to collimate the light beam emitted by the light-emitting chip on the fast axis. The existing fast-axis collimation process is generally It is done manually, which leads to problems such as low accuracy and low efficiency of collimation. Contents of the inventio...
