Agiltron Development Corporation — Department of Defense SBIR Phase I: Specially engineered rod type photonic fibers (PCF) hold the promise of becoming the next

Description

Specially engineered rod type photonic fibers (PCF) hold the promise of becoming the next generation gain medium for high pulse energy fiber lasers. This class of compact and highly efficient lasers is well suited for airborne and ground based infrared countermeasure (IRCM) applications. However, the current rod type PCF is only designed for Yb doped 1 m laser applications. The more important eye safe wavelength high pulse energy fiber laser is absent due either to low optical conversion efficiency at 1550 nm or unavailability of high power fiber components for a Tm doped rod type PCF based 2 m fiber laser. Agiltron Development Corporation proposes an advanced rod type Tm doped PCF based 2 m ultrashort and high pulse energy fiber laser based on our recently developed series of high power 2 m fiber components such as isolator, pump combiner and modulator. Agiltron-D will be able to demonstrate this new class of 2 m pulse fiber laser in very short time. In the Phase I, the fiber laser with mJ level pulse energy and ps pulse duration will be designed and demonstrated, and a 5 mJ pulse energy and fully functioned fiber laser system will be demonstrated in Phase II.
