Low 3.3 KV Threshold 100 KW Coaxial N2 Laser with a Resonator
Increased laser power with a very low threshold is obtained with a 1500 pf pulsed coaxial discharge applying a 22% reflection sapphire plate. The pulse width is increased from 3 ns to 6 ns by the resonator. The discharge is pulsed by a high current rise “Nanolite” pulser. The output is 80 kv with a 14 kv pulse voltage. The beam divergence amounts to approximately 1 mrad only. The energy conversion factor is increased to 0.35%.
