Detailed Schematic |
|
Generation of a double pulse pattern in the main beam by seeding the final amplifier A5 with two pulses of different intensities
from Double Pulse Generator

Schematic of amplifier gas flow (Ar + C3F7I which is photoionized) |
|
Schematic of 30 kV Xe flashlamps, 10 µs, 250-300 nm UV |
|
Oscillator and pulse selection system, with Pockels cells in center (see
theory) |
|
First vacuum spatial filter, beam expands from 8 to 22 mm. (see
theory) |
|
Output end of first power amplifier (double passed) (see
theory) |
|
Second spatial filter, 22 to 45 mm expansion. Relay mirror on left sends beam toward next amplifier. |
|
Output end of second amplifier, 2.7 m. White tubes leading to the room below re-supply the laser medium after each shot. |
|
Third spatial filter, 45 to 90 mm expansion |
|
Output end of third amplifier, 3.24 m |
|
Faraday rotator, between third and fourth amplifier. Box-like object on left is polarizer mount; coil generating the longitudinal magnetic field is downstream on right |
|
Forth spatial filter, 90 to 148 mm expansion |
|
Input end of fourth amplifier, 6.48 m. Black cables carry high voltage from capacitor banks (underneath) to six flashlamp sections. (see also) |
|
Fifth spatial filter, 148 to 290 mm expansion |
|
Fifth amplifier, 8.64 m. It is composed of eight sections each more than one meter long. The inner quartz tube contains Ar + C3F7I gas pressurized to three atmospheres
(see also Dr. Josef Krása of the IPP).
