A temperature controller for 980nm pump laser diodes is developed by using an integrated circuit ADN8831. The chip is used to control the temperature of the laser diode. Experimental results show that the temperature change of the laser diode is maintained within a temperature range of 0.1°C. The driver is successfully applied in a tunable fiber laser with an excellent temperature-stabilization effect.
