Abstract

A multiphoton intrapulse interference phase scan (MIIPS) adaptively and automatically compensates the combined phase distortion from a fiber supercontinuum source, a spatial light modulator pulse shaper, and a high-NA microscope objective, allowing Fourier-transform-limited compression of the supercontinuum pulses at the focus of the objective. A second-harmonic-generation-based method is employed to independently validate the transform-limited compression. The compressed pulses at the focus of the objective have a tunable duration of 10.838.9fs (FWHM), a central wavelength of 1020nm, an average power of 1870mW, and a repetition rate of 76MHz, permitting the application of this source to nonlinear optical microscopy and coherently controlled microspectroscopy.

(a)–(d) Comparison of the experimental SHG spectra (left column) and theoretical SHG spectra (middle column) corresponding to the spectral phases of four SC fundamentals (right column) for compressed (or TL) SC pulses (thin red), uncompressed SC pulses (thin blue), and shaped SC pulses (thick green). The spectral phases of the uncompressed pulses correspond to the retrieved spectral phases from MIIPS measurements. The shaded regions (or thin black curve) in the right column show the spectra of the four SC fundamentals, and the insets show the temporal profiles of the compressed SC pulses. SHG enhancement factors due to pulse compression are indicated in the left and middle columns.
