Fabrication of H+ implanted channel waveguides in Y3Al5O12:Nd,Tm single crystal buried epitaxial layers for infrared to blue upconversion laser systems

Fabrication and intense infrared to blue upconversion emission of proton-implanted Tm3+, Nd3+:Y3Al5O12 (YAG) channel waveguides are reported for the first time to authors’ knowledge. The single or multiple implanted channels are buried by positive induced index change in stacked planar layers grown...

Description
Summary:Fabrication and intense infrared to blue upconversion emission of proton-implanted Tm3+, Nd3+:Y3Al5O12 (YAG) channel waveguides are reported for the first time to authors’ knowledge. The single or multiple implanted channels are buried by positive induced index change in stacked planar layers grown by liquid-phase epitaxy on pure YAG substrates. The Nd3+ codoping considerably enhances the IR to blue upconversion emission of Tm3+ ions after excitation in resonance with either Nd3+ or Tm3+ absorption transition around 800nm.
