项目摘要

We studied physics of laser-diode (LD)-pumped multimode microchip solid-state lasers focussing on nonlinear dynamics inherent in optical complex systems possessing large degrees of freedom. Applications of LD-pumped microchip solid-state lasers has been also demonstrated. Research achievements include :1. Realization of single-frequency operation owing to high-density pumping. Design of stable single transversemode operation resulting from thermal lens effect.2. Theoretical and experimental demonstrations of nonlinear modal interactions resulting from nonlinear gain or quantum interference inherent in microcavity lasers and resultant dynamic instabilities.3. Observation of stimulated Raman-like oscillations and 1.5μm emissions from LD-pumped Nd microchip laser due to phonons created by non-radiative transition from the absorption to the upper laser-level.4. Experimental observation and theoretical confirmation of chaos synchronization and phase squeezed state in a microchip laser array with Doppler feedback5. Observation of noise-induced random chaotic burst generations and antiphase dynamics in multi-mode microchip solid-state lasers with optical feedback and theoreical verifications. Demonstration of quantum noise-induced ordering of chaotic oscillations in lasers with frequency-shifted feedback6. Realization of multimode green lasers without green problem featuring multitransition oscillations and demon stration of applicability to terahertz coherent wave generations.7. Realizations of ultrahigh sensitivity laser Doppler velocimetry, vibrometry and imaging ultilizing self-mixing modulation effects in microchip solid-state lasers
