Lm. Yang et al., CHIRPED-PULSE AMPLIFICATION OF ULTRASHORT PULSES WITH A MULTIMODE TM-ZBLAN FIBER UP-CONVERSION AMPLIFIER, Optics letters, 20(9), 1995, pp. 1044-1046
Microjoule pulse energies are achieved from a single-stage upconversio
n fiber amplifier for the first time, to our knowledge, in this demons
tration of chirped-pulse amplification with a multimode Tm:ZBLAN fiber
. A Ti:sapphire laser system provides the seed pulse for the fiber upc
onversion amplifier that produces picosecond pulse trains with energie
s as great as 16 mu J at a repetition rate of 4.4 kHz.
