Abstract:

Using Cr4+: YAG and acousto-optic jointly, the fiber coupling LD pumping Nd: YAG laser was actively-passively mode-locked. The output average power of passively mode-locked by Cr4+: YAG only, actively mode-locked by acousto-optic mode-locker only and mode-locked by Cr4+: YAG and acousto-optic jointly are compared and analyzed. The result shows good resolution to the low output energy and stability,and the mode-lock amplitude and energy fluctuation is less than± 6%, with the depth of mode locking of 100%, pulse width less than 410ps and output average power near 290mW.

Key words: laser techniques, actively-passively mode lock, Cr4+YAG, acousto-optic mode-locker, fiber coupling
