Lasers And Amplifiers Based On Hybrid Slab Active Mirrors

View page
US Patent:
6658036, Dec 2, 2003
Filed:
Jun 27, 2002
Appl. No.:
10/185743
Inventors:
Timothy J. Carrig - Lafayette CO
Allen K. Hankla - Lafayette CO
Assignee:
The United States of America as represented by the Secretary of the Air Force - Washington DC
International Classification:
H01S 306
US Classification:
372 66, 372 25, 372 99
Abstract:
A hybrid slab laser is made using a slab of active laser material, for instance Yb:YAG, capped by a nonactive material, for instance undoped YAG or sapphire. The two materials are bonded together, for instance by diffusion bonding. The composite slab is then cut and polished to serve as a laser gain module. The slab can be Brewster-cut or flat-flat and antireflection coated on the ends. Alternatively, the nonactive material can be sandwiched between two active regions. The slab is pumped from the top face like a disk laser or from the end like a longitudinally pumped slab. The slab could also be side-pumped using close coupled diodes. The preferred pumping mechanism depends on the pump source used. The slab generates or amplifies a laser beam that is longitudinally coupled into the device through the end (possibly Brewster-cut) surfaces. The laser beam bounces via total internal reflection within the slab passing one or more times through the active part(s) of the medium.

Phase And Birefringence Aberration Correction

US Patent:
55350496, Jul 9, 1996
Filed:
May 11, 1994
Appl. No.:
8/240898
Inventors:
Mark Bowers - Modesto CA
Allen Hankla - Livermore CA
Assignee:
The Regents of the University of California - Oakland CA
International Classification:
H01S 300
US Classification:
359334
Abstract:
A Brillouin enhanced four wave mixing phase conjugate mirror corrects phase aberrations of a coherent electromagnetic beam and birefringence induced upon that beam. The stimulated Brillouin scattering (SBS) phase conjugation technique is augmented to include Brillouin enhanced four wave mixing (BEFWM). A seed beam is generated by a main oscillator which arrives at the phase conjugate cell before the signal beams in order to initiate the Brillouin effect. The signal beam which is being amplified through the amplifier chain is split into two perpendicularly polarized beams. One of the two beams is chosen to be the same polarization as some component of the seed beam, the other orthogonal to the first. The polarization of the orthogonal beam is then rotated 90. degree. such that it is parallel to the other signal beam.
