Abstract: | Single-frequency bistability performances from a Tm,Ho:YLF laser with two Fabry?CPerot etalons near room temperature is reported. For the first time to our knowledge, the single-frequency bistability at 2.05???m is displayed in the laser operation with the bistable region width of 0?C580 mW and the jump power of 0?C78 mW, which can be tuned by regulating the length of the laser resonator. The maximum single frequency output power of 180 mW is obtained at the pump power of 2?W, and the laser frequency can be continuously tuned 1.25?GHz. The single frequency bistability laser can be used in laser lidar systems and all-optical switching systems. |
