| Number | Title | Issue Date |
| 7027477 | Expansion matched thin disk laser and method for cooling An optical system includes a diode pump source and a thin disk gain media. The thin disk gain media has first and second surfaces and is made of a material with an anisotropic thermal expansion. At least one of the first and second surfaces is a cooling surface. The... | 04/11/2006 |
| 6931037 | Diode pumped, multi axial mode intracavity doubled laser A diode pumped, multi axial mode, intracavity doubled, intracavity tripled laser, includes at least two resonator mirrors defining a resonator cavity. A laser crystal and a doubling crystal are positioned in the resonator cavity. A tripling crystal is also positione... | 08/16/2005 |
| 6922419 | Long pulse vanadate laser A diode-pumped solid-state laser has been invented that provides long Q-switched pulses at high repetition rate with high stability. The laser incorporates Nd:YVO4 as the gain medium. ... | 07/26/2005 |
| 6734387 | Method and apparatus for micro-machining of articles that include polymeric materials A micro-machining apparatus includes a mode-locked, infrared laser system with a high reflector and an output coupler that define an oscillator cavity which produces an output beam. A gain medium and a mode locking device are positioned in the oscillator cavity. A d... | 05/11/2004 |
| 6417955 | Stack pumped vanadate amplifier An amplifier uses a two-dimensional array of cw diodes to produce a pump beam. A coupler is positioned to receive the pump beam. The coupler reduces a cross-sectional dimension of the pump beam and creates a modified pump beam. A vanadate gain medium is p... | 07/09/2002 |
