Abstract
A narrow-linewidth photonic crystal fiber (PCF) laser operating at room temperature with two Bragg gratings integrated directly is demonstrated. Fabrication of the Bragg grating in a photonic crystal fiber is investigated experimentally by phase mask method. Under the optimal experiment condition, we fabricate the optical fiber grating with four obvious peaks. Moreover, a continuous-wave all fiber laser operation at 1549.6nm of a diode-pumped PCF laser is fabricated. A constrained bandwidth of 50 pm is formed through locking the laser on the overlapping peak of one Bragg grating with the side lobes of the other. It is possible to achieve a high stability and beam quality laser, which has a great application potential in optical communication field in future.
