Post-treatment of DBR fibre lasers for enhanced beat-frequency in dual-polarization operation
Abstract
UV photo-ablation provides an efficient and reproducible means to control the birefringence of a dual-frequency DBR fiber laser. The resulting beat note can be finely tuned by real-time measurement during the process from typically 100 MHz to about 6 GHz, independently of the active medium length.
