Red, green, blue upconversion laser pumped by single wavelength infrared laser source

Patent ·
OSTI ID:5040092
This patent describes a red green blue upconversion laser system pumped by a single pump laser source. It comprises a laser rod fabricated from a host material doped with a rare earth ion; a pump laser source for generating a pump beam substantially at a single infrared pump wavelength; a first upconversion laser mirror disposed adjacent a first end of the laser rod through which the pump beam passes into the laser rod, the first mirror characterized b high transmissivity at the pump beam wavelength and high reflectivity at the red, green and blue upconversion wavelengths; and a second upconversion laser mirror mounted adjacent a second end of the laser rod and characterized by a transmissivity in the range of 1% to 10% at the red, green and blue upconversion wavelengths.
