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.

Nd:Yag Crystal

This research studied characteristics of the Nd:YAG laser with second harmonic generation (SHG) at 532 nm. It can be develop as a standard wavelength according to the recommendation made by the Comite International des Poids et Measures (CIPM). This study investigates various parameters that effect wavelength and laser power of the Nd:YAG laser such as injection current of diode laser, temperature of Nd:YAG crystal and second harmonic generator crystal. Its wavelength can be tuned in the range of standard wavelength at 532.24503 nm with 10-7 of stability.
