Transverse flowing liquid Kerr cell for high average power laser Q-switching and for direct modulation of high power laser beams.

Patent Comaskey, Brian J.

A fluid flow concept is applied in an optical apparatus to define a high gain stand-off, fast electro-optical q-switch which is highly impervious to high average power optical loads.

All fiber passively Q-switched laser

Patent Soh, Daniel B. S.; Bisson, Scott E

Embodiments relate to an all fiber passively Q-switched laser. The laser includes a large core doped gain fiber having a first end. The large core doped gain fiber has a first core diameter. The laser includes a doped single mode fiber (saturable absorber) having a second core diameter that is smaller than the first core diameter. The laser includes a mode transformer positioned between a second end of the large core doped gain fiber and a first end of the single mode fiber. The mode transformer has a core diameter that transitions from the first core diameter to the secondmore » « less

Method and system for suppression of stimulated Raman scattering in laser materials

Patent Caird, John A.; Bayramian, Andrew J.; Ebbers, Christopher A.

A composition of matter is provided having the general chemical formula K(H,D).sub.2P(.sup.16O.sub.x,.sup.18O.sub.y).sub.4, where x<0.998 or y>0.002, and x+y.apprxeq.1. Additionally, a method of fabricating an optical material by growth from solution is provided. The method includes providing a solution including a predetermined percentage of (H,D).sub.2.sup.16O and a predetermined percentage of (H,D).sub.2.sup.18O, providing a seed crystal, and supporting the seed crystal on a platform. The method also includes immersing the seed crystal in the solution and forming the optical material. The optical material has the general chemical formula K(H,D).sub.2P(.sup.16O.sub.x,.sup.18O.sub.y).sub.4, where x<0.998 or y>0.002, and x+y.apprxeq.1.
