Abstract
- Abstract: We describe a method of ultrashort-pulse and ultrafast-pulse-train generation through optical parametric amplification of a laser beat wave. Numerical simulation shows that 250-fs laser pulses at 1.55μm are generated from a beat-wave seeded optical parametric amplifier pumped by a 30-ps laser at 1064nm. The pulse compression is attributable to sideband generation and parametric amplification under group velocity mismatch. Our experimental result confirms efficient generation of comb-like sidebands for the mixing waves from such an optical parametric amplifier. [Copyright &y& Elsevier]
