Abstract

The invention relates to a laser module group, particularly to a laser module with a controllable power. On the basis of the technical scheme, the laser module group is composed of an LD, an LD driver panel, a sensor, a bearing seat, an optical cement crystal, a semi-transparent and semi-transparent glass sheet, and a bracket. A light-transmitting hole is formed in the bottom of the bearing seat; and the LD is installed inside the bearing seat. The sensor is welded to the LED driver panel that is installed below the bearing seat; and the sensor corresponds to the light-transmitting hole. The optical cement crystal is installed on the LED; a notch corresponding to the light-transmitting hole is formed in the optical cement crystal; the bracket is installed on the optical cement crystal; and the semi-transparent and semi-transparent glass sheet is installed on the bracket. A certain angle is formed between the semi-transparent and semi-transparent glass sheet and a laser beam emitted by the LD, so that the laser beam reflected by the semi-transparent and semi-transparent glass sheet is emitted on the sensor through the notch and the light-transmitting hole. The laser module group has advantages of simple and compact structure, small size, and simple production process; and the batch production efficiency is effectively improved.

Description

technical field [0001] The invention relates to a laser module, in particular to a power controllable laser module. Background technique [0002] At present, the power controllable laser module has complex structure, cumbersome process, and large volume, making it difficult to achieve mass production. Contents of the invention [0003] The invention provides a power-controllable laser module, which has a simple and compact structure, a small volume, a simple production process, and effectively improves mass production efficiency. [0004] Technical scheme of the present invention is as follows: [0005] A power-controllable laser module, including LD, LD drive board, sensor, bearing seat, laser crystal, transflective and semi-reflective glass sheet and bracket, the bottom surface of the bearing base is provided with a light-transmitting hole, and the LD is installed on the In the bearing seat; the sensor is welded on the LD driver board, the LD driver board is installed ...
