Fiber Bragg Grating team 

---

Yongbin Lin and Dr. Robert Bunch

Design and construct intra-cavity second-harmonic Ar+ (488 nm) system to fabricate Fiber Bragg Gratings for 1320 nm single-mode fiber.  Design and test 5 Fiber Bragg Gratings ( FBGs ) for the construction of TTD arrays that provide time delays between 2-channels for full steering angular bandwidth.  Construct a stage for the Brewster angle BBO crystal for intra-cavity mounting.  Design an interferometer with variable fringe spacing for fiber exposure at 244 nm.
