A multipurpose directional coupler based on integrated optics technology is described. The
coupling characteristics of the device is controlled by a narrowband microwave biasing …

A single pulse was selected from the train of mode-locked pulses of a Nd-glass laser using
optics external to the oscillator cavity. Its pulse width was measured by the two-photon …

We have generated femtosecond subharmonic pulses by using an optical parametric
oscillator. The optical frequencies of the idler and the signal are one third and two thirds …

We demonstrate femtosecond operation of a direct space-to-time pulse shaper in which
there is direct mapping (no Fourier transform) between the spatial position of the masking …

A new method for the coherent characterization of subpicosecond optical pulses after
propagation through a nonlinear medium (ie, with frequency broadening) is described. The …

A general interferometer composed of linear filters (both time stationary and frequency
stationary) and a square-law detector is analyzed, and the possibilities for measuring the …

A passive pulse-shaping system capable of producing optical pulses of arbitrary temporal
profile on the subnansecond time scale is described and analyzed. The system uses a pair …

We report a simple extension of the Z-scan technique where pulse trains characteristic of a
Q-switched and mode-locked Nd: YAG laser are employed to investigate the dynamics of …

We analyze the properties required of a linear interferometer composed of time-stationary
and time-nonstationary filters and a square-law, integrating detector in order that it may be …
