Abstract

The invention relates to a semiconductor laser device aging tool which is characterized by comprising a main control panel, a communication connection board, multiple water cooling boards, an operation panel and a machine cabinet. The main control panel, the communication connection board and the operation panel are respectively assembled in the machine cabinet. Each water cooling board is installed in the machine cabinet via a guide rail. The main control panel is connected with an upper computer via a 485 communication mode. The communication connection board connects the water cooling boards and the main control panel via flat cables. The operation panel controls power-on and power-off of the whole system of the aging tool, and the state of each aging device is indicated. Simultaneous aging of multiple semiconductor laser devices can be realized, aging parameters of each laser device can be independently set, and current, voltage, power and temperature of the laser devices can be monitored simultaneously.

Description

technical field [0001] The invention relates to the technical field of electromechanics, in particular to a semiconductor laser aging tool, which can simultaneously age 64 semiconductor lasers, and can set and monitor aging parameters at the same time. Background technique [0002] Existing semiconductor laser aging is powered by a constant current power supply. It is necessary to manually turn on and off the power supply to set the aging current of the laser. In order to age more semiconductor lasers, the lasers are usually connected in series to increase the aging voltage. However, there are certain risks in series connection. The number of components that can be aged by a constant current power supply is limited, and the parameters during the aging process cannot be monitored. Therefore, there is an urgent need to invent a device capable of simultaneously aging multiple semiconductor lasers, and it is necessary to set aging parameters for each device separately and be abl...
