High Power 4.2-Cycle Mid-Infrared Pulses From a Self-Compression Optical Parametric Oscillator
Published 2018-01-01Get full textWe demonstrate the generation of few cycle mid-infrared (MIR) pulses from a self-compressed optical parametric oscillator (OPO), synchronously pumped by a 105 fs Yb<sup>3+</sup> doped fiber laser system. By using a ring cavity design, 4.2-cycle (45.3 fs) MIR pulses at a centra...

Generation of 110-W sub-100-fs Pulses at 100 MHz by Nonlinear Amplification Based on Multicore Photonic Crystal Fiber
Published 2016-01-01Get full textWe report a multicore photonic crystal fiber (PCF) amplification system delivering about 110-W laser pulses with a duration of sub-100 fs. This amplifier is seeded by a large mode area (LMA) PCF mode-locked oscillator with a repetition rate of 100 MHz. By a one-stage nonlinear amplification, the pul...

Advanced Backcross QTL Analysis for the Whole Plant Growth Duration Salt Tolerance in Rice (Oryza sativa L.)
Published 2014-08-01Get full textSalinity is a major factor limiting rice yield in coastal areas of Asia. To facilitate breeding salt tolerant rice varieties, the whole-plant growth duration salt tolerance (ST) was genetically dissected by phenotyping two sets of BC2F5 introgression lines (ILs) for four yield traits under severe na...
