Dye laser picosecond convertor

SPIE Proceedings, 1994
The operation characteristics of a dye laser device designed for converting a fixed wavelength pump pulse emitted from a nanosecond non-mode lockable laser such as nitrogen, excimer laser into high-power picosecond laser pulses spectrally adjustable between 386 to 700 nm are presented.

Synchronous tunable picosecond laser

Soviet Journal of Quantum Electronics, 1977
A picosecond rhodamine 6GDN dye laser was constructed. It was excited longitudinally by a train of pulses of the second harmonic of the neodymium laser radiation and the pulses emitted by both lasers were fully synchronized. The divergence of the dye laser radiation was minimized by matching the optical lengths of the resonators.

The picosecond laser for tattoo removal

Lasers in Medical Science, 2016
The prevalence of tattoos continues to grow as modern society's stigma towards this form of body art shifts towards greater acceptance. Approximately one third of Americans aged 18-25 and 40 % of Americans aged 26-40 are tattooed. As tattoos continue to rise in popularity, so has the demand for an effective method of tattoo removal such as lasers.

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.
