From: Two-color multiphoton in vivo imaging with a femtosecond diamond Raman laser
Laser characterization (a) Fiber amplifier autocorrelation, the pulse-width is 120 fs assuming a sech2 pulse shape, (b) Cross-correlation between fiber amplifier and diamond Raman laser, the pulse width is 220 fs, estimated to be 110 fs after decorrelation. (c) Diamond Raman laser autocorrelation, the pulse-width is 100 fs assuming a sech2 pulse shape. (d) Measured and calculated spectra of the fiber amplifier, diamond Raman laser, and effective 2C2P excitation. The 2C2P spectra were calculated from a cross-correlation of the measured fiber amplifier and diamond laser spectra.
