【Abstract】 By focusing the static beam of Cr:LISAF laser on fiber medium, the mode competition will take place. Effective compression of laser pulses using backward SBS of broad-band and multi-transverse mode Cr:LISAF laser pulses is realized. Compression under different pump voltage is discussed in this paper. Influence of focal length and influence of radius and length of fiber on pulsewidth compression are also analyzed.更多还原
