Pj. Bennett et al., FEMTOSECOND PULSE DURATION MEASUREMENTS UTILIZING AN ULTRAFAST NONLINEARITY OF NICKEL, Optics communications, 147(1-3), 1998, pp. 148-152
A new, broadband background free autocorrelation technique for measuri
ng pulse durations of visible and infrared femtosecond laser pulses is
described, The technique is based on the use of a reflective polariza
tion-sensitive interaction in metallic nickel. (C) 1998 Elsevier Scien
