多芯光子晶体光纤锁模激光器
Mode locked multi-core photonic crystal fiber laser
摘要
Abstract
A mode locked fiber laser based on Yb-doped large mode area photonic crystal fiber operating in the all-normal dispersion regime is experimentally studied. The eighteen cores of the gain fiber are arranged in array-type geometry with an equivalent mode diameter of about 52 μm. A sigma laser cavity is used without using any elements for dispersion compensation. Reliable self-starting mode-locking is achieved using a fast semiconductor saturable absorber mirror. The laser directly produces 4. 92 ps chirped pulses at a 44. 68 MHz repetition rate for an average power of 3. 3 W corresponding to a pulse energy of 74 Nj. The pulses are compressed to 780 fs with a grating pair outside the cavity.关键词
