Abstract
An RGB light source for a luminaire projector system includes Red, Green and Blue lasers each outputting a randomly polarized (RP) single mode (SM) light with at least a 4 nm spectral linewidth. The Green laser has a MOPFA-structured pump which outputs a pulsed pump beam at a fundamental wavelength in a 1 μm wavelength range and further includes a SHG. The SHG includes an LBO nonlinear crystal receiving the pulsed pump beam and outputting a train of pulses of BB Green light. The Red laser is configured with a QCW fiber laser pump and a frequency converter with an LBO nonlinear crystal outputting a train of pulses of red light in a 6xx nm wavelength range.
