Improvement in the laser system for the A0 TTF photoinjector

PDF Version Also Available for Download.

Description

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 oscillator or by changing the distance between two compression gratings, the UV laser pulse length can be varied in the range of 3ps to 30ps. Also the strong correlation between the UV laser energy and the ... continued below

Also the strong correlation between the UV laser energy and the IR laser pulse length has been studied, and the result is applied to achieve the UV laser energy of 18 {micro}J/pulse.
