Source abstract
Abstract
Abstract We demonstrate a diode-end-pumped continuous laser operating a new wavelength at 1370 nm in Nd: YLF. It is a coherent radiation exactly lies in the absorption band of the C 70 and water vapor. A maximum output power up to 4 W is achieved at an incident pump power of 14.6 W, with a slope efficiency of 35.5%, and the optical-optical efficiency of 27.4%. The laser output power instability in half an hour is less than 3%. Calculated by experimental threshold data, the stimulated emission cross section of 1370 nm transition in Nd: YLF crystal is determined to be 0.4437×10 −20 cm 2 .
