High power, high wall-plug efficiency, mass producible, reliable and low-cost lasers with wavelength of 2 to 2.5mm are needed for laser accelerator with Si optics.  The technology would benefit the DOE’s High Energy Physics program.  The objective of this project is to develop a novel Tm-doped ceramic laser material and a diode-pumped solid-state laser that operates at 2 mm.  In Phase I, Tm-doped ceramic laser materials will be developed via pseudo-reaction-sintering.  Then, a longitudinally-pumped, solid state, Tm-doped ceramic diode laser will be designed for demonstration. 

Commercial Applications and Other Benefits as described by the awardee:  The Tm ceramic laser should find use in both defense and civilian applications, including coherent laser radar, remote wind sensing, remote sensing of “smart dust”, trans-canopy ranging, stand-off coherent laser inspection of laminated-composite aircraft components, materials processing, ultrafast laser machining, medical therapeutics, entertainment, image recording, and remote sensing.
