Abstract :
Output power of 550 W has been achieved from a nuclear-pumped multiple path laser system containing3He-Ar by using the3He(n, p)3H nuclear reaction for power deposition. Lasing was achieved in Ar at 1790 nm. The complex beam profile was resolved by an InAs array detector. Lasing threshold thermal neutron fluxes as low as 
n/cm2. s have been demonstrated for 79.8 kPa (600 torr)3He- (2 percent)Ar mixtures with peak fluxes of 
n/cm2. s. Laser output was directly proportional to thermal neutron flux, and also increased proportionally with increasing3He pressure up to 292.6 kPa (2200 torr). The variation of the laser output power with the number of passes through the excited medium was found to peak at 5-7 passes.
