Laser Technology and Applications (Group 82)

The Laser Technology and Applications Group develops application-specific solid-state lasers and beam control and diagnostics for high-energy laser systems. Examples of research activities include creating cryogenic-laser-based illuminators for sensor applications, demonstrating wavelength and coherent laser-beam-combining techniques for scaling fiber amplifier and diode laser arrays to higher brightness, and developing a ground terminal for an advanced NASA laser experiment to a moon-orbiting satellite. These activities span the range from demonstrating innovative laser devices in the laboratory to designing and field-testing complete optical systems.

Laser Technology

Development of advanced laser technology is at the core of the Laser Technology and Applications Group. Historically, some of the key laser technologies developed by the group include the invention of the Ti-sapphire laser in the early 1980s, development of the passively Q-switched microchip laser, demonstration of the first room temperature Yb:YAG laser, and development of high-power diode lasers and quantum cascade lasers.

Beam Combining

The group has led the laser community in the development of beam-combining techniques, to take the outputs from arrays of lasers and combine them into essentially a single beam with near-ideal propagation characteristics. Such beam combining is a decades-old problem, but over the past decade, the group has had multiple successes. (more)
