The XL-PLT9 520CA-810mW semiconductor laser is a high-performance 520nm green single-mode laser diode. It comes in a metal TO-90 coaxial package, with a typical continuous wave output power of 810mW (TC=25℃), a typical threshold current of 0.18A, an operating current up to 1.4A, and an operating voltage up to 6.6V. This device features a high modulation bandwidth and a low beam divergence angle (fast axis 35~44°, slow axis 5~9°). Compared to the 1.2W version, it has slightly lower power but requires less drive current and makes thermal management easier. It's ideal for applications like LiDAR, industrial inspection, medical biophotonics, research, and defense where beam quality and power are quite important.
