Diagnostic Chain for Recording Luminescence Space Distribution
Original language description
In this contribution we present the result of recording of YAG:Ce luminescence making visible the laser beam profile of LTB MNL 100 nitrogen laser with wavelength of 337,1 nm. The lasing is achieved in high-voltage (10-20 kV) high-speed (few-ns) transverse gas discharges in nitrogen, so the beam profile is not homogeneous. Yttrium aluminum garnet activated by cerium was chosen because it is a fast scintillator with excellent mechanical and chemical resistance applicable in vacuum. Maximum emission wavelength of YAG:Ce is 550 nm and decay time is 70 ns. The thickness of scintillation crystal was 0,8 mm. Front illuminated full frame CCD with resolution 4014 x 2684 and with 9 mm pixel size was used as a detector. Luminescence of YAG:Ce excited with energyand length of pulses of 1,4 mJ and 25 ns was recorded. Vertical and horizontal beam profiles were depicted with 30 Hz repetition frequency and 20 s exposure time. Also luminescence excited with single shot in 2 s exposure time was record
