Passive Q-switched Modelocking Diode-end-pumped Yb∶YAG with Surface-state Type of Semiconductor Saturable Absorption Mirror
用表面态型半导体可饱和吸收镜实现Yb∶YAG激光器被动调Q锁模

A new type of surface-state semiconductor saturable absorption mirror was introduced, with which passive Q-switched modelocking of diode-end-pumped Yb∶ YAG laser was realized. At the 1.4 W of pumping power, Q-switched modelocking seires was obtained, which has 1 mW average output and 200 MHz frequency.
