Time-resolved measurements of picosecond optical breakdown
Picosecond optical breakdown was investigated in order to assess its potential for performing highly localized incisions for laser surgery. Measurements of breakdown were performed using single 40-ps… Expand
Ultrashort pulse propagation, pulse breakup, and fundamental soliton formation in a single-mode optical fiber
The propagation of ultrashort (0.83 ps), intense dye laser pulses through a single-mode optical fiber is investigated. The input wavelength is tuned in the vicinity of the zero dispersion wavelength… Expand
Refractive indices of orthorhombic KNbO 3 . I. Dispersion and temperature dependence
We have measured the refractive indices of potassium niobate in the orthorhombic phase at six different temperatures between 22 and 180°C in the wavelength range 400–3400 nm. Sellmeier coefficients… Expand
Laser-Tissue Interactions in the Nanosecond, Picosecond and Femtosecond Time Domains
The use of high peak power laser pulses in the short and ultrashort time domains has opened a variety of novel laser-tissue interactions with potential for application in clinical medicine.… Expand

The effects of picosecond laser‐induced optical breakdown on tissue were investigated using high‐intensity 40 ps Nd:YAG laser pulses at 1.06 μm. Tissue damage was evaluated using the corneal… Expand
Chromophores with Strong Heterocyclic Acceptors: A Poled Polymer with a Large Electro-Optic Coefficient
Syntheses of a series of conjugated donor-acceptor chromophores, based on a strongly electron-withdrawing heterocyclic acceptor, have led to compounds with large second-order optical nonlinearities.… Expand
Refractive indices of orthorhombic KNbO 3 . II. Phase-matching configurations for nonlinear-optical interactions
Based on temperature-dependent refractive-index data of orthorhombic KNbO3 [ J. Opt. Soc. Am. B9, 380 ( 1992)], we analyze various nonlinear-optical second-order interactions. Phase-matching curves… Expand
Generation of optical solitons in the wavelength region 1.37–1.49 μm
First‐order soliton pulses of 77–250 fs duration have been generated in the wavelength region from 1.37 to 1.49 μm. These solitons are formed by transmitting dye laser pulses at 1.34 μm of 1 ps… Expand
1.3-MUm subpicosecond pulses from a dye laser pumped by compressed Nd:YAG-laser pulses.
Tunable dye-laser pulses of 300 fsec have been generated by synchronously pumping with pulses of a mode-locked Nd:YAG laser compressed to 5 psec. The tuning range lies between 1.25 and 1.35 μm.… Expand
200-femtosecond pulses at 1.06 MUm generated with a double-stage pulse compressor.
Starting with 90-psec pulses of a Nd:YAG laser, 200-fsec pulses are generated in a double-stage fiber-grating-pair pulse compressor. This corresponds to a compression factor of 450. A peak power… Expand
