Abstract
A laser projector including a green diode pumped microchip laser module projecting a green laser beam, an optical sensor receiving the laser beam, a power control circuit for the green diode pumped microchip laser module receiving a signal from the optical sensor relative to the power output of the laser beam, and control electronics receiving the signal from the optical sensor connected to the power control circuit modulating the power output of the green diode pumped microchip laser module to maintain a substantially constant power output from the green diode pumped microchip laser module.
