Abstract

Disclosed is a phosphate laser neodymium glass which comprises oxides including the compositions of (mol%) P2O5: 55-65; Al2O3: 4-10; MO (M=Mg, Zn): 7-15; R20(R=Li, Na, K): 18-30; R203(R=B, La, Y, Sb, Nd): 2-3. The glass provided by the invention can be used for high-power laser devices.

Description

technical field [0001] The invention relates to laser neodymium glass, in particular a phosphate laser neodymium glass with high stimulated emission cross section, low second-order nonlinear refraction index and small thermal-optical coefficient, which is suitable for high-power laser devices. Background technique [0002] As the scale of high-power laser devices continues to expand, the laser output energy continues to increase. After the laser energy density per unit surface area reaches a certain level, the self-focusing damage of the material caused by nonlinearity when the beam propagates in the material must be paid attention to. Under the action of high laser intensity, the refractive index of the material changes with the laser intensity according to the following formula: [0003] n=n 0 +n 2 φ(1) where n 2 is the second-order nonlinear refractive index, n 0 is the refractive index of the material when no laser passes through, and Φ i...
