@article{1041, author = {E. Potma and Conor Evans and Sunney Xie and R. Jones and Jun Ye}, title = {Picosecond-pulse amplification with an external passive optical cavity}, abstract = {We experimentally demonstrate the amplification of picosecond pulses at high repetition rates through the coherent addition of successive pulses of a mode-locked pulse train in a high-finesse optical cavity equipped with cavity dumping. Amplification greater than 30 times is obtained at a repetition rate of 253 kHz, boosting the 5.3-nJ pulses from a commercial mode-locked picosecond Ti:sapphire laser to pulse energies of more than 150 nJ. © 2003 Optical Society of America}, year = {2003}, journal = {Optics Letters}, volume = {28}, pages = {1835}, month = {2003-01}, issn = {0146-9592}, doi = {10.1364/OL.28.001835}, }
