532 Nm

We have experimentally demonstrated an efficient all-fiber passively Q-switched Yb-doped fiber laser with Samarium doped fiber as a saturable absorber. Average output power of 3.4 W at a repetition rate of 250 kHz and a pulse width of 1.1 microseconds was obtained at a pump power of 9.0 W. By using this fiber laser system and an MgO-doped congruent periodically poled lithium niobate (MgO:c-PPLN), second harmonic generation (SHG) output at 532 nm was achieved at room temperature. The conversion efficiency is around 4.2% which agrees well with the theoretical simulation.

We report second harmonic generation (SHG) from ZnO thin films deposited by the pulsed laser deposition technique at ambient oxygen pressures ranging from 10 mTorr to 1 Torr on glass substrate at room temperature (RT). The dependence of SHG on grain size and thickness of the film is discussed.
