Red-green-blue generation from a lone dual-wavelength GdAl_(3)(BO_(3))_(4):Nd~(3+) laser

摘要

We demonstrate the simultaneous generation of the three basal red-green-blue colors from a lone GdAl_(3)(BO_(3))_(4):Nd~(3+) bi-functional laser and optical nonlinear crystal. The laser works in a dual-wavelength operation in the two ~(4)F_(3/2)→~(4)I_(11/2) (near 1062 nm) and ~(4)F_(3/2)→~(4)I_(13/2) (near 1338 nm) channels, under a fixed wavelength pumping (at 744.7 nm) and with a fixed crystal orientation. Red and green results from self-frequency doubling of the two laser channels, blue results of self-sum frequency mixing of the pump and the 1338 nm laser.
