چکیده

We have designed a laser system for the Linac Coherent Light Source rf photoinjector consisting of a Ti:Sapphire oscillator and 2 amplifiers using Chirped Pulse Amplification. The output after tripling will be 0.5 mJ tunable UV pulses at 120 Hz, with wavelength around 260 nm, pulsewidth of 10 ps FWHM and 200 fs rise and fall times. Amplitude stability is expected to be 1% rms in the UV and timing jitter better than 500 fs rms.

High-power parametric amplification of 11.8-fs laser pulses with carrier-envelope phase control.

Phase-stable parametric chirped-pulse amplification of ultrashort pulses from a carrier-envelope phase-stabilized mode-locked Ti:sapphire oscillator (11.0 fs) to 0.25 mJ/pulse at 1 kHz is demonstrated. Compression with a grating compressor and a LCD shaper yields near-Fourier-limited 11.8-fs pulses with an energy of 0.12 mJ. The amplifier is pumped by 532-nm pulses from a synchronized mode-lock...

Novel laser system for ultrafast spectroscopy

The design and performance of a cavity-dumped Ti:sapphire (CD-TS) oscillator and short pulse-pumped amplifier system is presented. Dumped pulses as short as 12 fs duration and 60 nJ in energy, with 70%-80% dumping efficiency are made possible by a stretched dumper-arm configuration. The oscillator yields stable, reliable, and reproducible pulses. Pulse duration and phase structure are analyzed ...

Spectral amplitude and phase noise characterization of titanium-sapphire lasers.

There are few methods capable of characterizing pulse-to-pulse noise in high repetition rate ultrafast lasers. Here we use a recently developed method, termed fidelity, to determine the spectral amplitude and phase noise that leads to lack of pulse repeatability and degrades the performance of laser sources. We present results for a titanium sapphire oscillator and a regenerative amplifier syst...

Improvement in the laser system for the A0 TTF Photoinjector

The production of high charge and high brightness electron beams places increasingly challenging demands on the drive laser used at the A0 photoinjector in the Fermilab. The IR and UV laser pulse lengths need to be optimized for such purpose. We have experimentally investigated two different ways to change the UV laser pulse length on the cathode; either by changing the bandwidth of the oscilla...

Coherent Synchrotron Radiation in an X-Band Photoinjector

A high-gradient, high-brightness X-band rf photoinjector is used to produce sub-picosecond electron bunches at energies in the 1.5 2 MeV range, which are propagated in a short section of corrugated waveguide, with an inner diameter of 10 mm, a corrugation period of approximately 2.5 mm, and a modulation depth of 1.5 mm. Extremely short rf pulses are measured, in the 100 ps < 5 ns range, corresp...
