High-power 905nm Wavelength Pulsed Semiconductor Laser Module for Laser Rangefinder

摘要

Tunnel junction multiple active regions semiconductor laser diode is introduced as lighting source and the collimating system is used to enhance laser power density. A repetitive frequency 1KHz, pulsed width 20-100ns, rising edge 8ns and 30A narrow pulse driving circuit has gained. In this way a laser module for laser rangefinder has completely achieved and it has high characteristic for increasing measurement range in laser rangefinder.
