The XL-PLPT9 450MD-7W semiconductor laser is an ultra-high-power 440nm blue-violet single-mode laser diode. It comes in a metal TO-90 coaxial package and has a typical CW (continuous wave) optical output of 7W (TC=25℃). The typical threshold current is 0.30A, operating current ≤4.0A, operating voltage ≤4.8V, and the maximum junction temperature is 135℃. This device is currently the most powerful model in the series (7W) and features high modulation bandwidth and low beam divergence (fast axis 41~54°, slow axis 6~11°). It's perfect for applications that demand high-power blue-violet light sources, like LiDAR, industrial processing, medical biophotonics, research, and defense.
