来源：ChineseOpticsLetters 年份：2003
When femtosecond laser pulses interfere with chirped femtosecond laser pulses in As_(2)S_(3) fiber, a chirped fiber grating is formed. An analytical expression is given to describe the chirped grating, and its Bragg reflectivity is calculat......
Ultra-broadband optical spectrum generation from a stretched pulse fiber laser utilizing zero-disper
