| Outline of Final Research Achievements |
Development of component technologies and demonstration of laser power scaling were performed for trivalent Praseodymium doped fluoride lasers pumped by blue InGaN diode-lasers (LD) to renovate visible and deep ultraviolet coherent light sources that have been provided by 2nd-4th harmonics of near-infrared lasers.By employing four 3.5-W InGaN LDs, CW lasers at red(4.8W) and green (1.8W), active Q-switching(1W, 5kHz) and its intracavity-SHG(60mW, 7,7kHz), passive Q-switching(1.2W, 105kHz) and its SHG(76mW, 50kHz), and CW mode-locking were achieved.
