Abstract

Remote monitoring of carbon dioxide (CO₂) is becoming increasingly important for homeland security needs as well as for studying the CO₂ distribution in the atmosphere as it pertains to global warming problems. So, efficient solid-state lasers emitting in the 1.55 - 1.65 μm spectral range, where CO₂ absorption lines are, (i), plentiful and, (ii), carry significant relevant information, are in great demand. Reported here is the first laser performance of resonantly pumped Er³⁺-doped scandia (Sc₂O₃) ceramic. The laser was operated in the cryogenically-cooled regime with the quantum defect (QD) of only 4.5%, which, along with superior thermal conductivity of scandia, offers significant eye-safe power scaling potential with nearly diffraction limited beam quality. Slope efficiency of 77% and Q-CW output power of 2.35 W were obtained at 1605.5 nm which has significant utility for counter-IED applications.
