| Abstract: | We present a high power red-green-blue (RGB) laser light source based on cascaded quasi-phasematched wavelength conversions
in a single stoichiometric lithium tantalate. The superiority of the experimental setup is: the facula of the incident beam
is elliptical to increase interaction volume, and the cavity was an idler resonant configuration for realizing more efficient
red and blue light output. An average power of 2 W of quasi-white-light was obtained by proper combination of the RGB three
colors. The conversion efficiency for the power of the quasi-white-light over pump power reached 36%. This efficiency and
powerful RGB laser light source has potential applications in laser-based projection display et al. |
