XL-PLPT9 455LB-6W

The XL-PLPT9 455LB-6W semiconductor laser is an ultra-high-power 455nm blue single-mode laser diode. It uses a metal TO-90 coaxial package, with a typical optical output power (continuous wave) of 6W (TC=25℃), a typical threshold current of 0.35A, operating current ≤3.5A, and operating voltage ≤4.8V. This device features a high modulation bandwidth and low beam divergence (fast axis 46°, slow axis 10°). It's currently the most powerful laser diode in its series and is ideal for applications requiring high-power blue light, such as LiDAR, industrial processing, medical biophotonics, research, and defense.
