EverGreen (70-200 mJ @ 532 nm)
A state of the art laser for PIV
The EverGreen is a dual pulsed laser for PIV applications with a choice of pulse energies and repetition rates: 70 mJ, 145 mJ or 200 mJ at 15 Hz and 100 mJ at 25 Hz. The system consists of a single laser head with a single power supply. The EverGreen delivers a perfect combination of precisely overlapped 532 nm beams in a rugged, compact package. In addition Quantel also offers a version with 30 mJ at 266 nm with a repetition rate of 15 Hz.
