Experimental details of KrF Oscillator - Amplifier laser configuration

چکیده
The experimental details of KrF laser “oscillator – amplifier” configuration used in UCSD mirror damage facility are given. Two commercial KrF lasers are used for running oscillator-amplifier mode of operation. The pulses from Compex KrF excimer laser is sliced using a Pockels cell to FWHM 5ns and passed through the LPX excimer cavity for amplification. The experimental details, gain analysis and other aspects of such system like temporal and spatial profiles, energy stability are discussed. Laser pulse energy of 60 mJ is extracted from the amplifier for an input energy of 0.8mJ with 5 ns pulse with ‘pure’ Gaussian temporal profile.

Large-Area Electron Beam Diode and Gas Cell Design for a KrF Laser IFE System*
In a KrF laser inertial fusion energy (IFE) power plant [1] an array of N laser amplifiers would focus and symmetrically illuminate a fusion target with a total of ~3 MJ of laser light. The lasers are pumped by large-area electron beam diodes, whose technology is presently being developed on the Electra [1] and Nike [2] facilities at the Naval Research Laboratory in Washington, DC. Sufficient p...

We present measurements of the power noise that is due to optical amplification in a laser-diode-pumped Nd:YAG free-space traveling-wave linear amplifier in a master-oscillator-power-amplifier configuration. The quantum noise behavior of the optical amplifier was demonstrated by use of InGaAs photodetectors in a balanced detection configuration, at a total photocurrent of 100 mA and in a freque...
متن کاملUpgrade of the nhelix laser system at GSI
The first high energy laser system that became operational at GSI is the ”nanosecond high energy laser for heavy ion experiments” (nhelix). This system has recently been improved significantly. Due to major changes in the system layout, the quality in terms of temporal and spatial beam homogeneity was improved, while at the same time the output energy was raised up to 120 J. This could be achie...

The possibility of the same large-aperture KrF laser driver to amplify simultaneously both nanosecond pulses for thermonuclear target implosion and picosecond ones for fuel ignition is discussed relative to KrF-based Fusion Test Facility. In this way experiments were performed at hybrid Ti:Sapphire/KrF GARPUN-MTW facility on amplification of subpicosecond pulses. 2-TW, 330-fs pulses were produc...
