Nanosecond laser systems can provide tens-of-mJ pulse energies and are often used for sample excitation, nonlinear phenomena study, material processing and LIBS measurements, often combined with frequency converters such as OPO or harmonic generators.
Nanosecond laser systems can provide tens-of-mJ pulse energies and are often used for sample excitation, nonlinear phenomena study, material processing and LIBS measurements, often combined with frequency converters such as OPO or harmonic generators. Theu usually offer much lower repetition rates than femtosecond systems. Usually, mode quality is sacrificed for higher output energies.
In Tampere University we are using few nanosecond lasers, for example:
Ekspla 340, 10Hz pulse laser system with TGH 355nm pump OPO, tuning range 410-720 nm, up to 30 mJ pulse energy
Ultra 100 (Quantel), ns pulse laser offering output at 1064 nm, 532 nm and 355 nm, with respective pulse energies 100 mJ, 55 mJ and 30 mJ, at 20 Hz repetition rate.
Q-smart 100 (Quantel), ns pulse laser, sub-10 ns pulses at 20Hz rep rate, 60 mJ pulse energy at 532 nm.
