Adiabatic soliton compression by means of a pressure gradient in a hollow-core photonic bandgap fiber is investigated theoretically and numerically. It is shown that the duration of the compressed pulse is limited mainly by the interplay between third-order dispersion and the Raman-induced soliton frequency shift. Analytical expressions for this limit are derived and compared with results of detailed numerical simulations for a realistic fiber structure.

    ABSTRACT: The coupled nonlinear Schrödinger equations with the harmonic potential and variable coefficients are studied for the pulse propagation in an inhomogeneous medium. With the modified Hirota method and symbolic computation, the bilinear form and analytic one-soliton solutions are obtained. A type of pulse compression technique is proposed, which can have the optical pulses compressed without any external devices. Moreover, the compressed pulses are pedestal free. The influences of the inhomogeneity of the refractive index, Kerr nonlinearity and diffraction are analyzed as well. The proposed technique may provide a different method for the pulse compression.

    ABSTRACT: We review the use of hollow-core photonic crystal fibers (PCFs) in the field of ultrafast gas-based nonlinear optics, including recent experiments, numerical modeling, and a discussion of future prospects. Concentrating on broadband guiding kagomé-style hollow-core PCF, we describe its potential for moving conventional nonlinear fiber optics both into extreme regimes—such as few-cycle pulse compression and efficient deep ultraviolet wavelength generation—and into regimes hitherto inaccessible, such as single-mode guidance in a photoionized plasma and high-harmonic generation in fiber.

    ABSTRACT: This chapter covers the benefits and applications of ultrafast laser scanning microscopes from a biomedical perspective. The basic architecture of a laser microscope is discussed, including how to design a laser scanning system with lateral and axial control. Also investigated is the design of custom collection optics for optimizing the detection of emitted photons and maximizing that emitted fluorescence in the presence of photobleaching. In addition, this chapter addresses three techniques novel to the biomedical community. The first is the technique of temporal focusing and its application toward wide-field imaging and micromachining. Also investigated is the concept of photon counting in multiphoton microscopy and how this approach to imaging has become practical for everyday use. Finally, several different methods are revealed for implementing spectral imaging with a multiphoton microscope platform.
