Abstract
The present paper discusses laser kinetic modeling of diode pumped flowing medium aprotic liquid laser containing Nd3+ ions in POCl3 solvent host. Transverse pumping has been examined, which is ideal from point of view of laser scalability to higher power levels. In the computations, spectroscopic parameters of aprotic solution having an Nd3+ ion concentration of 0.3 M have been considered and numerical calculations were performed for analyzing the effect of various parameters including; active ion concentration, gain medium length, absorption depth, output coupler transmission and input pump power on laser output and efficiency. The results indicate that nearly 1.5 kW laser output may be obtained for an input pump power of 5.0 kW with a slope efficiency of nearly 31% having a threshold pump power requirement of 300 W for a given cell length of 15 cm. Hence, a set of optimized parameters have been obtained for designing an efficient transversely diode pumped kW level flowing liquid laser.
