【Abstract】 A testing system is designed for investigating the dependence of the laser output power on the temperature values of the cavity.The temperature of the cavity is controlled by the electronic current supplied by the power supplier. At the same time,the output power versus the resistance value of the temperature sensor can be obtained by the computer data collecting system and the resistance value is transformed to temperature value of the cavity.The dependence of the output power varied with the cavity temperature is analyzed,the optimized working temperature of the laser system is found out.Meanwhile it is used to measure lasers.The system can measure many lasers at the same time,thus the debugging speed and the production efficiency are improved.更多还原
