Ultra compact, efficient, and reliable GaN based deep UV laser for Raman spectroscopy

Leveraging Agiltron"s industrial leading developments and production of Raman instruments, external cavity laser and nonlinear optical components, we propose to develop a new class of high performance compact deep ultraviolet (UV) laser for Raman spectroscopy. The approach is closely coupled with recent progress in GaN blue laser and external resonator enhanced second harmonic generation (SHG) to push the deep UV laser performance well beyond current state-of-the-art. The proposed deep UV laser incorporates a GaN based external cavity laser with resonator enhanced SHG. This innovative design has multiple improvements that overcome the deficiencies associated with conventional approaches in system size and wall plug efficiency. The technical approach will be proved in Phase I through numerical analysis, design and experimentation. A compact prototype deep UV laser will be produced in Phase II for delivery to Army.
