Isolated attosecond pulse is generated from neon gas driven by CEP stabilized sub-5fs Ti:Sapphire laser pulses at repetition rate of 1 kHz. The streaking retrieval shown the pulse duration is 173as with photon energy of 82eV.
Carrier-envelope phase stabilization of a two-stage chirped pulse amplifier laser system with regenerative amplification as the preamplifier is demonstrated with a 90 mrad rms error for a locking period of 4.5 h.
By combining control of the Ti:sapphire crystal temperature with the modulation of the pump laser power, the carrier-envelope offset frequency fCEO was locked for more than 19 hours.
Coherent extreme-ultraviolet (XUV) radiation was studied by interaction of carrier-envelope (CE) phase stabilized high energy sub-5-fs infrared (800 nm) laser pulses with neon gas at a repetition rate of 1 kHz. The results show generation of isolated attosecond XUV pulses.
This paper reports the carrier-envelop phase (CEP) locking for the 5 fs re-compressed laser pulse generated from a chirped pulse amplified (CPA) Ti:sapphire laser at 1 kHz repetition rate. A phase locking feedback system with two loops was designed to control the fast fluctuation arising from the seeding laser and the slow fluctuation arising from the sub-mJ amplified pulse. The principle and structure...
We present a picosecond optical parametric amplifier pumped by a 360 mJ frequency-doubled Ti:sapphire laser at 60 ps duration. Tunable signal wavelength from 460 nm to 750 nm was realized, maximum output energy up to 30 mJ.
