Abstract: According to one embodiment of the present invention, a programmable light source comprises one or more semiconductor lasers (10, 110), a wavelength conversion device (20, 120), and a laser controller (130). The controller is programmed to operate the semiconductor laser (10, 110) using a modulated feedback control signal. The wavelength control signal is adjusted based on the results of a comparison of a detected intensity signal with a feedback signal to align the lasing wavelength with the conversion efficiency peak of the wavelength conversion device (20, 120). Laser controllers (130) and projections systems operating according to the control concepts of the present invention are also provided.
