Effect of dispersion on the operation of a KTP electro-optic Q switch
Abstract:
The effect of dispersion on the operation of a KTP electro-optic Q switch was investigated. A KTP crystal in the normal orientation has been successfully operated as a Q switch. The experiment was performed with a laser resonator containing a Nd:YLF crystal end pumped with a cw diode-laser array. A pulse length of approximately 100 ns was obtained at a repetition rate of 1 KHz. Temperature tuning was used to eliminate static phase retardation. The effect of dispersion was found to affect Q switching. Wavelength stabilization was performed to counteract the effect of dispersion. These measures allowed us to achieve Q switching action.
