The operation of a Ti:sapphire-pumped, femtosecond optical parametric oscillator (OPO) based on the nonlinear material KTiOPO4 is described. By empirically optimizing the parametric interaction geometry, we have extended the maximum idler wavelength

We have demonstrated bistability in a phase-conjugate resonator containing an intracavity saturable absorber. The saturable absorber was a film of fluorescein-doped boric acid glass. The state of the resonator is determined by an external control bea

We report a new family of organometallic compounds that exhibit optical limiting through reverse saturable absorption. The optical limiting properties of the metal cluster compounds HFeCo(3)(CO)(12), [NEt(4)](+)FeCo(3)(CO)(12),(-) HFeCo(3)(CO)(10)(PM

We have conducted measurements of the linear electro‐optic coefficient (r41) and electrogyratory coefficient (η41) in Bi12TiO20 at 633 nm. A precise knowledge of these coefficients is important for evaluating the holographic recording properties o

A broadly tunable, ultrafast optical parametric oscillator is used to measure carrier-density-dependent absorption spectra in a 340-meV band gap (GaInSb/InAs)/AlGaSb superlattice multiple quantum well structure. Similar structures have been implement

We have used the 830 nm, subpicosecond output of a mode‐locked Ti:sapphire laser, together with subpicosecond 3.55 μm pulses from a synchronously pumped optical parametric oscillator, to perform room‐temperature, time‐resolved, differential tr

Lasers as Tools for Manufacturing of Durable Goods and Microelectronics.
We demonstrate the use of a nonsteady-state photo-induced-emf adaptive photodetector as a robust, low-cost laser ultrasonic sensor. This class of sensor enables high-fractional bandwidth ultrasound detection and, in addition, all-optical compensation

Review of Progress in Quantitative Nondestructive Evaluation ISBN: 9781461380276
The trend toward intelligent manufacturing has produced an increase in the need for sensors which can nondestructively evaluate components and processes in real-time. One commonly used nondestructive approach is ultrasonic inspection. The most common

Nonlinear Optical Materials for Switching and Limiting.
We examine optical limiting with C60 solutions for nanosecond optical pulses at 532 nm and 694 nm and microsecond pulses at 514 nm. When the input fluence is less than 50 J/cm2, optical limiting is due to a combination of reverse saturable absorption
