The LS-LD-IRR10-LF type laser life aging device developed by LiSen Optics is a laboratory aging device used to test the lifespan of lasers. This device allows for the setting of the test laser's driving current, operating temperature, and the number of data collection points or frequency. Based on testing needs, the laser under test is set under constant working conditions (e.g., I=500mA, T=80°C), and the relative optical power P of the laser is monitored in real-time over time t, thereby drawing the high-temperature accelerated aging curve (P-t curve) of the test laser. Based on the principle of accelerated life testing, the lifespan of the laser under test under normal working conditions (e.g., T=25°C) is calculated using the aging failure formula.
