Presentations:Ultrafast Optics VIII, Monterey California, September 25-30, 2011
Tu03 - Tuesday, September 27, 2011 @ 9.10 am Internal validation of shaper-based pulse characterization and compression Shaper-based techniques enable straightforward in situ pulse characterization and compression, without a need for a dedicated experimental setup, beam splitting and recombining. Their widespread adoption, however, has been hindered by concerns that such measurements have to be cross-checked by independent means to ensure measurement validity. We argue and demonstrate that such consistency validation can be achieved internally by analysis of several readily available experimental observables (second-harmonic generation spectra, shaper-assisted frequency-resolved interferometric autocorrelation, etc.) and calculations aimed at verifying self-consistency. Tu10 - Tuesday, September 27, 2011 @ 12.10 pm Real-Time MIIPS Measurement and Correction of Pulse Phase and Amplitude Distortions This invited presentation will cover the development of an automated method for measuring and controlling amplitude and phase fluctuations from an ultrafast laser in real time. The method is based on a single shot measurement based on MIIPS, and the use of an online pulse shaper that makes the necessary corrections in order to maintain TL pluses at the target. The system is shown to maintain peak intensity constant even when phase (second and third order dispersion) and amplitude of the laser beam are being changed by moving external optics. Tu10 - Tuesday, September 27, 2011 @ 14.55 pm New generation of fiber lasers with automated pulse compression for biomedical imaging This talk highlights the performance of an all-normal-dispersion fiber laser that produces 22-nJ pulses at 42.5 MHz rep. rate. [B. Nie et al., Optics Express 19, 12074 (2011)]. These pulses are characterized and compressed via MIIPS to as short as 42 fs, with 10 nJ per pulse. The compressed pulses are shown to generate the second and third harmonic spectra spanning 30 and 20 nm, respectively. Further advances to produce shorter pulses and their use for two-photon and third harmonic generation biomedical imaging will be presented. |
