Paper Abstract

In this paper, characteristics of the intra-cavity frequency doubled Nd:YYO4/PPMgO:LN green laser have been studied experimentally and theoretically. Two types of green laser strucutures, namely optical contact structure and separated structure, have been packaged for low power (100 mW) and high power (~1 W) applications, respectively. Coupled mode equations are used to investigate the green laser. The effect of the thermal dephasing along the propagation direction in the PPMgO:LN due to the heat generation by the linear absorption of the fundamental wave and linear and nonlinear absorption of the second hamonic (SH) wave is analyzed theoretically. By introducing the longitudinal temperature chirp in the PPMgO:LN crystal, the temperature tuning curve is enlarged by using a uniform PPMgO:LN grating.
