2μm波长激光对人眼安全,在相干探测风切变、非线性频率转换等方面有重要应用。2μm波长激光还可应用到激光医疗,由于其吸收深度浅,手术精度高于发射1μm波长的激光。Tm∶YAP的发射截面(5×10-20cm2)是Tm∶YAG(2.2×10-20cm2)的2倍,抽运波长795 nm更接近商品化的800 nm附近的激
The 2μm wavelength laser is safe for the human eye and has important applications in coherent detection of wind shear and nonlinear frequency conversion. 2μm laser wavelength laser can also be applied to medical, because of its shallow absorption depth, surgical precision than the launch of 1μm wavelength laser. The emission cross-section of Tm: YAP (5 × 10-20 cm 2) is twice that of Tm: YAG (2.2 × 10-20 cm 2) and the pumping wavelength of 795 nm is closer to the commercial excitation at 800 nm
