WebJan 27, 2024 · In this paper a single-channel chirped pulse amplification laser system based on Yb-doped photonic crystal fiber was constructed, which achieved a pulse energy output of 1 mJ with a beam quality close to the diffraction limit. Pulsed synchronous pumping was used to suppress amplified spontaneous emission at a repetition rate of 1 kHz. The … WebOct 6, 2024 · Photonic crystals (PCs) are the artificial dielectric formation of periodic refractive index arrangement of multi-dimensional structures. One of the unique properties of PCs is a photonic bandgap (PBG) demonstrated by the glorious work of Zhou and Schoepf [ 1 ], Yablonovitch et al [ 2] and Kopp [ 3 ].
