| Outline of Final Research Achievements |
Optimization of material and fabrication of fundamental microdisk resonator was carried out in pursuit of low lasing threshold for CW drive excitation of organic microdisk laser element. Specifically, three of (1) Search for materials with low light absorption loss, (2) Improvement of surface roughness, (3) Improvement of stability of WGM were carried out. In conclusion, many findings on low lasing threshold for CW excitation were obtained, and the direction was indicated.
