In this paper, we study the birefringence in photonic crystal fiber lasers PCFs and in conventional fiber lasers in the bi-directional pump scheme in the linear
The ideal behavior of communication system requires a single frequency carrier. In optical communication system, light is used as a carrier. Practical laser sou
Propagation characteristics of finite Airy-Gaussian beams through an apertured misaligned first-order ABCD optical system are studied. In this work, the general
