Short-cavity picosecond dye laser design

Applied Optics, 1979
The design of a short-cavity dye laser is described. The laser produces a 2-psec pulse which is tunable in the range between 400 nm and 470 nm when pumped with an 8-psec 355-nm third-harmonic pulse from a modelocked Nd(+3) :glass laser. The laser features a variable calibrated cavity length (10-500 microm), a dye cell through which dye can be ...

Ultrastructure of Picosecond Laser Intrastromal Photodisruption

Journal of Refractive Surgery, 1996
ABSTRACT PURPOSE: To investigate the ultrastructure of the corneal stroma after picosecond intrastromal photodisruption with a neodymium-doped yttriumlithium-fluoride (Nd:YLF) laser. METHODS: We performed picosecond intrastromal photodisruption on six human eye-bank eyes using a lamellar technique.

Picosecond pulsed diode ring-laser gyroscope

Optics Letters, 1991
We have demonstrated a novel solid-state ring-laser gyroscope, which utilizes as the gain media a pair of semi-conductor diodes in an external ring cavity. The use of homogeneously broadened gain media is made possible by actively mode locking the laser.

Mode-locked picosecond diamond Raman laser

Optics Letters, 2010
We present a mode-locked diamond Raman laser synchronously pumped by a mode-locked laser running at 532 nm and pulse duration 26 ps. The diamond laser generated up to 2.2 W of average power with output pulses of duration 21 ps at a yellow wavelength of 573 nm. The output pulse duration varied notably with small changes in cavity length and decreased to

Picosecond Neodymium:Yttrium Lithium Fluoride Laser Sclerectomy

American Journal of Ophthalmology, 1993
The picosecond neodymium:yttrium lithium fluoride laser, a high-power, short-pulse laser that uses low energy per pulse and has a high repetition rate and a highly coherent energy source of 1,053 nm, was used to perform sclerectomies by an ab externo approach in human cadaver eyes.

Laser picosecond acoustics in multilayer structures

Ultrasonics, 2002
The field of laser picosecond acoustics has thrived owing to the ease of detection of propagating picosecond acoustic pulses through changes in optical reflectance. Reflectance changes are caused by the inhomogeneous modulation of the refractive index by the propagating elastic strain through the photoelastic effect and also by the associated induced ...
