Abstract
We quantitatively predict the observed continuum-like spectral broadening in a 90-mm weakly birefringent all-normal dispersion-flattened photonic crystal fiber pumped by 1041-nm 229-fs 76-MHz pulses from a solid-state Yb:KYW laser. The well-characterized continuum pulses span a bandwidth of up to 300 nm around the laser wavelength, allowing high spectral power density pulse shaping useful for various coherent control applications. We also identify the nonlinear polarization effect that limits the bandwidth of these continuum pulses, and therefore report the path toward a series of attractive alternative broadband coherent optical sources.
Highlights
The apparent promise of the fiber continuum as a coherent broadband compressible pulsed source amendable for arbitrary pulse shaping remains largely unfulfilled. Such source is indispensible in coherent control ultrafast spectroscopy and microscopy [3], but is technically challenging in the form of mode-locked
To generate near transform-limited (TL)
The corresponding scalar GNLSEquantified fiber continua can guide the pulse compression procedure necessary for ultrabroadband coherent control in ultrafast spectroscopy and microscopy
Summary
White-light generation by the combination of a photonic crystal fiber (PCF) and an oscillatortype ultrafast laser was reported in 2000 [1], and has since initiated the so-called supercontinuum revolution [2]. The apparent promise of the fiber continuum as a coherent broadband compressible pulsed source amendable for arbitrary pulse shaping remains largely unfulfilled Such source is indispensible in coherent control ultrafast spectroscopy and microscopy [3], but is technically challenging in the form of mode-locked solid state lasers [4,5].
