Research Paper: Compensation of Thermal Phase Mismatch Effects in The High Power Second Harmonic Generation Using a Chirped Periodically Poled Non-linear Crystal
Thermal effects strongly influence the process of second harmonic generation, especially at high fundamental Cooler powers.The generation of non-uniform temperature distribution in the crystal due to the absorption of fundamental and second harmonic waves leads to significant degradation of the efficiency of the second harmonic generation process.T
