The influence of resonator parameters on the stability of Q-switched intracavity-frequency-doubled lasers

The stable condition of Z-shaped A-O Q-switched intracavity-frequency-doubled laser is analyzed with the matrix optics.The in fluence of the resonator's length,curvature radii of mirrors and the thermal length of the laser cystal on the system stability is analyzed with numerical calculation.It is proved that the shorter cavity is easier to achieve high output power and high transition efficiency.
