Cryogenically Cooled Tm,Ho:YAP Laser Achieves 15 W Continuous-Wave Output at 2.12 μm

In 2013, Li et al. presented a study on a cryogenically cooled, double-end pumped b-cut Tm,Ho:YAP laser. The researchers were able to achieve a continuous-wave (cw) output power of 15 W at 2.12 μm, with a beam quality factor M2 of 1.3. This achievement is significant as it demonstrates the potential for high-power laser systems that can operate in the mid-infrared region. The use of cryogenic cooling and double-end pumping allowed for improved thermal management, resulting in higher output power and better beam quality. The results of this study could have important implications for applications such as laser surgery, remote sensing, and laser spectroscopy. Further research in this area could lead to the development of even more efficient and powerful laser systems.
