Compact all-diode-pumped femtosecond laser source based on chirped pulse optical parametric amplification in periodically poled KTiOPO/sub 4/
2002 Edition, January 1, 2002 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. We report for the first time to our knowledge on chirped pulse optical parametric amplification (CPOPA) in periodically poled KTiOPO/sub 4/ (PPKTP). PPKTP exhibits higher damage threshold and weaker photorefiractive effect than PPLN, and the lower electric fields required...
