Title: Method and apparatus for tuning high power lasers

Full Record
Other Related Research

Abstract

This invention relates to high power gas lasers that are adapted to be tuned to a desired lasing wavelength through the use of a gas cell to lower the gain at a natural lasing wavelength and "seeding" the laser with a beam from a low power laser which is lasing at the desired wavelength. This tuning is accomplished with no loss of power and produces a pulse with an altered pulse shape. It is potentially applicable to all gas lasers.

Method and apparatus for generating high power laser pulses in the two to six micron wavelength range

Patent MacPherson, David C [Conifer, CO]; Nelson, Loren D [Evergreen, CO]; O'Brien, Martin J [Bailey, CO]

Apparatus performs a method of generating one or more output laser pulses in a range of 2 to 6 microns. When a plurality of the output laser pulses are generated, a first output pulse has any selected wavelength within the range and a second output pulse is temporally closely spaced relative to the first output pulse and has a chosen wavelength differing from the selected wavelength. An oscillator laser cavity is provided with a tunable oscillator rod capable of generating initial laser pulses within a range of from 750 to 1000 nm, and a tuning element is coupled to themore » « less

Method and apparatus for reducing coherence of high-power laser beams

Patent Moncur, Norman K [Ann Arbor, MI]; Mayer, Frederick J [Ann Arbor, MI]

Method and apparatus for reducing the coherence and for smoothing the power density profile of a collimated high-power laser beam in which the beam is focused at a point on the surface of a target fabricated of material having a low atomic number. The initial portion of the focused beam heats the material to form a hot reflective plasma at the material surface. The remaining, major portion of the focused beam is reflected by the plasma and recollected to form a collimated beam having reduced beam coherence.

Method and apparatus for reducing diffraction-induced damage in high power laser amplifier systems

Patent Campillo, Anthony J [Los Alamos, NM]; Newnam, Brian E [Los Alamos, NM]; Shapiro, Stanley L [Los Alamos, NM]; ...

Self-focusing damage caused by diffraction in laser amplifier systems may be minimized by appropriately tailoring the input optical beam profile by passing the beam through an aperture having a uniform high optical transmission within a particular radius r.sub.o and a transmission which drops gradually to a low value at greater radii. Apertures having the desired transmission characteristics may readily be manufactured by exposing high resolution photographic films and plates to a diffuse, disk-shaped light source and mask arrangement.
