| Summary: | 碩士 === 國立高雄師範大學 === 物理學系 === 101 === In this thesis, we have investigated the dynamical behaviors of laser-diode-pumped microchip Np-cut Nd：KGW lasers.
In the absence of optical feedback, spiking oscillations were observed in Np-cut Nd：KGW lasers. If the pump power is more than twice the pump power of the laser threshold, the laser exhibited relaxation oscillations intermittently.
After introducing the Doppler optical feedback, we found that the residence time of relaxation oscillations increased when the frequency of Doppler optical feedback was increased.
