A new compact green laser is demonstrated by using a mGreen module based on compact packaged MgO doped
periodically poled lithium niobate (MgO:PPLN). The green laser can generate over 700-mW green light with an opticalto-
optical efficiency of 29.6% and a volume of less than 7 cm3. The excellent performances of the MgO:PPLN based
lasers, including high efficiency, compact size, low cost and being suitable to mass production, are very attractive for
laser display applications.
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.
