Abstract

Abstract

Improving the wide - temperature operation ability of fiber lasers can effectively enhance the environmental adaptability and operation reliability of fiber lasers under extreme high- and low-temperature conditions, ensure their stable output under complex working conditions, and provide support for technological innovation and industrial upgrading in related fields. Recently, the National University of Defense Technology achieved a near-single-mode all-fiber laser oscillator that can operate stably within the temperature range of −50 to +50 ℃ by directly pumping with fiber-coupled semiconductor lasers. The output power reached 2 kW, which is the highest output power level of fiber lasers operating in a wide temperature range reported publicly so far.
- Fiber laser,
- optical fiber oscillator,
- wide temperature operation.
