Detection of Damage of Rd6G Film Using Surface Second-Harmonic Generation
표면 제2고조파 발생을 이용한 색소 Rd6G박막층의 손상 분석
Abstract
The damage of a thin film of Rd6G dye was probed by Surface Second-Harmonic Generation(SSHG) method. A portion of the Rd6G thin film on glass substrate was damaged by 532 nm laser beam, and the damage was probed by detecting intensity variation of SSHG. The result was confirmed through direct observation with optical microscope.oscope.
색소 Rd6G박막층에서의 표면손상을 제2고조파 발생법을 응용하여 분석하였다. 유리기판 위에 스핀코팅 방법으로 Rd6G박막을 만들고 Rd6G의 강한 흡수선 근방의 Q-switched Nd:YAG 레이저의 제2고조파(532nm)를 입사시켜 손상영역을 만들었다. 여기에 기저빔
