Since the first isolated attosecond pulse was demonstrated through high-order harmonics generation (HHG) in 2001, researchers’ interest in the ultrashort time region has expanded. However, one realizes a limitation for related research such as atto

We present an energy-scaling experiment on a femtosecond infrared pulse using dual-chirped optical parametric amplification (DC-OPA). A total output energy exceeding 100 mJ with 36-fs pulse duration was achieved in the infrared region, which is the h

Attosecond laser pulses allow to explore the ultrafast atomic or molecular processes occurring in chemical reactions. Here the authors utilize a sequence of two XUV pump-probe pulses to control the dissociation dynamics of the hydrogen molecular ion.

By employing a dual-chirped optical parametric amplification (DC-OPA) using MgO:LiNbO3 crystals, we generate 31 mJ mid-infrared (MIR) pulses at 3.3 um with a repetition rate of 10 Hz. After passing through a CaF2 bulk compressor which has 70% through

Generation of high-flux soft X-ray high harmonics driven by loosely focused TW-class infrared pulses

We develop an experimental strategy for generating high-flux soft x-ray high-order harmonics (HH) driven by loosely focused high-energy infrared femtosecond pulses. Strong soft x-ray HHs are generated in a long Ne medium.

We discuss the efficient generation of intense “water window„ (0.28⁻0.54 keV) isolated attosecond pulses (IAPs) using a mid-infrared (MIR) waveform synthesizer. Our numerical simulations clearly indicate that not only a longer-wavelength drivin

By combining the dual-chirped optical parametric amplification and two kinds of nonlinear crystal (type-I BiBO and type-I MgO), a one-octave bandwidth (1.45 μm – 3 μm), carrier-to-envelope phase (CEP) stable infrared (IR) laser pulses have been a
Based on the dual-chirped optical parametric amplification and type-I BiB$_3$O$_6$(BiBO) crystals, the generation of $>$100 mJ, 10.4 fs, 10 Hz, carrier-to-envelope phase (CEP)-stable laser pulses, which are centered at 1.7 $μ$m, is demonstrated; it

By employing the dual-chirped optical parametric amplification and type-I BiBO crystals, an over 100 mJ, 10.4 fs, 10 Hz, carrier-to-envelope phase (CEP) stable laser pulses centered at 1.7 μm is achieved, which results in a peak power of 10 TW. In a
