An i-depth study of the localization properties of a random laser cavity is equivalent to the introduction of the theoretical analysis rate equation under external optical feedback lasers designed for magnetic optical crystal isolation devices to achieve improved random lasers. Using Nd:YAG laser, experimental results demonstrate that improved laser scattering loss can be reduced to achieve directional UV laser output. Finit-difference tim-domain simulation results further show that the TE mode waveguide optical gain is approximately twice the planar waveguide, the coupled signal and pump intensity in improving the guide structure is significantly improved, and the output power results confirm the structure to reduce random laser scattering losses. Results of the application of random laser have an obvious reference value.

Abstract: An i-depth study of the localization properties of a random laser cavity is equivalent to the introduction of the theoretical analysis rate equation under external optical feedback lasers designed for magnetic optical crystal isolation devices to achieve improved random lasers. Using Nd:YAG laser, experimental results demonstrate that improved laser scattering loss can be reduced to achieve directional UV laser output. Finit-difference tim-domain simulation results further show that the TE mode waveguide optical gain is approximately twice the planar waveguide, the coupled signal and pump intensity in improving the guide structure is significantly improved, and the output power results confirm the structure to reduce random laser scattering losses. Results of the application of random laser have an obvious reference value.
