TLDR
Alexandrite pumping of Cr3+:LiSrAlF6 (Cr:LiSAF) is investigated by studying the most probable limiting parameters, including gain, optical damage, and heat load capacity.Abstract:
Alexandrite pumping of Cr3+:LiSrAlF6 (Cr:LiSAF) is investigated by studying the most probable limiting parameters, including gain, optical damage, and heat load capacity. An alexandrite-pumped, 200-mJ, Q-switched Cr:LiSAF oscillator–amplifier has been demonstrated.read more

TL;DR: An investigation of the water durability suggests that the cooling solution should be maintained at pH = 7 to ameliorate problems associated with water dissolution, and a design for a 50-W Cr:LiSAF laser system is proposed that is based on a detailed knowledge of all the relevant material parameters.

Ground-state depleted solid-state lasers: principles, characteristics and scaling
William F. Krupke,Lloyd L. Chase +1 more
TL;DR: In this paper, a novel class of rare-earth-doped solid-state laser is described, where the ground-state depleted laser is pumped by an intense (more than tens of kW cm−2) narrow-band (less than a few nm) laser source and is characterized by an unusually low laser ion doping density (5 to 10×1018 ion cm−3), an unusually large fractional excited population inversion density (4 to 8× 1018 ion kg−3, or >75%), a gain element that is optically thick at the pump
