The invention relates to the technical field of semiconductor laser testing, and provides a pump laser aging temperature control system. The pump laser aging temperature control system comprises a water cooling machine; at least two water cooling plates, wherein each water cooling plate is used for allowing a pump laser to be attached to the water cooling plate for aging test, the first water inlet of each water cooling plate is communicated with the second water outlet of the water cooler, and the first water outlet of each water cooling plate is communicated with the second water inlet of the water cooler; a temperature monitoring device which is at least used for monitoring the temperature of each pump laser in real time; and at least two temperature adjusting structures which are communicated between the first water inlet of each water cooling plate and the second water outlet of the water cooling machine in a one-to-one correspondence manner, and are used for adjusting the water inlet temperature of each water cooling plate according to the temperature monitoring result of the temperature monitoring device. The pump laser aging temperature control system can be used for the aging temperature control of the pump lasers with different aging temperature requirements at the same time, so that the pump laser aging temperature control system is wider in application range and good in adjustability.
Description
technical field [0001] The application belongs to the technical field of semiconductor laser testing, and more specifically, relates to a temperature control system for pumping laser aging. Background technique [0002] The pump laser is a semiconductor laser. The aging of the pump laser is a very important part of the pump laser manufacturing process. It is often necessary to work for a long time at high temperature and high current to make the pump laser age to a relatively stable performance curve. area. The aging temperature of pump lasers with different wavelengths is different. For example, 915 pump lasers need to be aged in the temperature range of 50-60°C, while wavelength-locked pump lasers need to be aged in the temperature range of 20-30°C. However, the aging fixtures currently on the market can only be used for aging pump lasers within the same temperature range, resulting in different pump lasers needing to use different aging fixtures for aging, wasting the co...
