Research Summary

Takunori  Taira(Ph.D.)

"Micro Solid-State Photonics", based on micro domain structure and boundary controlled materials, such as laser ceramics and quasi phase matching (QPM) devices, enhances optical effects for creation of new functions in the micro- or microchip lasers. Lately, we invented the multiple-chip gain medium for distributed face cooling (DFC), which could manage the high-gain and high-field laser with compact system, by our original atomic-level direct-bonding. Basic Laser Development Team will develop the compact power lasers based on these Tiny Integrated LAsers (TILA) to provide the extreme giant-power, and open their fruitful future of “Giant Micro-photonics” for the advanced electron accelerators.
