The GSA and ESA dual-wavelength pumped Tm: YAP laser emitting in the 2.3 μm region have been realized successfully. The Tm∶YAP crystal has a maximum output power of 2.28 W at 2.3 μm. To the best our knowledge, this is the highest CW output power obtained in a 2.3 μm Tm-doped solid-state laser. Making full use of the broadband emission spectrum of the ³H₄→³H₅ transition of the Tm∶YAP crystal, a watt-level LD-pumped 2.5 μm Tm∶YAP laser is achieved using the dual-wavelength pumping scheme. Our results show that GSA and ESA dual-wavelength pumping is an effective technical means to achieve a high power output of 2.3 μm Tm-doped laser.
