Dear Colleagues Since its first installation in 2005 we are experimenting problems caused by side pulses in the femto-picoseconds scale in the time profile of our Coherent Legend USP (2.5 mJ, 1KHz) amplifier output. These satellite pulses are visible in the autocorrelation trace at ±600 fs, ±1200 fs and ±12 ps and we can not get them below 1% of the main pulse intensity. The origin seems to be related with some etaloning produced in the optics (pocket cells, waveplates, crystal…) of the amplifier cavity. We would like to know if somebody else has suffered from the same problem. Thanks in advance, best regards Asier Longarte -------------------------------- Dr. Asier Longarte Facultad de Ciencia y Tecnología Departamento de Química Física Barrio Sarriena S/N 48940 Leioa Phone: +34 94 601 2529 Fax: +34 94 601 3500 To join or leave the molecular-dynamics-news email list, go to: http://www.jiscmail.ac.uk/lists/molecular-dynamics-news.html
