A simple theoretical model of the ultraviolet laser radiation generated by self-frequency sum mixing in a single argon-pumped Nd3+-doped nonlinear crystal is proposed. Self-absorption by both absorption edge and Nd3+ bands lying in the ultraviolet range is taken into account. The model is then applied to Nd3+:YAl3(BO3)4, Nd3+:GdCa4O(BO3)3, and Nd3+:YCa4O(BO3)3 borate laser crystals. The crystal length, pump wavelength, and Nd3 concentration that optimize the pump to ultraviolet efficiency are determined for each case. The ultraviolet output power is found to be tens of milliwatts for a pump power of 2 W.
