摘要：

We explored efficient nanosecond pulse generation in a passively Q-switched cladding-pumped Yb-doped fiber laser by use of an external-cavity configuration containing a Cr4+ : YAG saturable absorber crystal. By exploiting passive Q-switcbed regime and stimulated Brillouin scattering, pulses of durations as short as 2.7 ns, corresponding to a peak power of similar to 9 kW, have been achieved. The laser was tunable over 70 nm and green output power generation was obtained by external frequency doubling in a KTP crystal.
