극초단 펄스 레이저의 파장변환을 위한 이축 비선형 광학 결정에서 분산의 새로운 계산법
A novel method for calculation of dispersions in biaxial crystals for frequency conversion of short pulse lasers
초록
As laser pulse width becomes shortened from nanoseconds to femtoseconds, the effects caused by the dispersions of nonlinear optical mediums, such as group velocity mismatch and group velocity dispersion become considerably significant. The group velocity mismatch and group velocity dispersion are the major factors that lead to a decrease of frequency conversion efficiency and pulse spreading for picosecond and femtosecond pulses.
