| Outline of Final Research Achievements |
Self-pumped phase conjugate mirror having fast response time was successfully constructed using a broad-area laser diode with angled feedback configuration. Measured phase conjugate reflectivity has been at most 80%. Therefore, self-oscillation of the phase conjugate optical cavity is not yet experimentally realized. Since optical spectra of the present phase conjugate cavity exhibited multiple LD-longitudinal modes, blazed grating was employed as wavelength selective reflector, which led to the demonstration of the single longitudinal mode operation both in LD-longitudinal and external cavity modes. The linewidth was measured to be 210 kHz using delayed self-heterodyne method.
