Abstract

A new, to our knowledge, neodymium-doped lanthanum calcium borate crystal (Nd3+:La2CaB10O19, Nd:LCB) has been grown by the flux method. The spectroscopic parameters for Nd:LCB crystal have also been calculated based on Judd–Ofelt theory. The intensity parameters Ωt are Ω2=4.96×10-20 cm2, Ω4=3.94×10-20 cm2, and Ω6=3.71×10-20 cm2. The radiative lifetime τr is 349 µs. The absorption band at 800 nm has a FWHM of 12 nm. The absorption cross section is σa=2.40×10-20 cm2, and the emission cross sections at 1070 nm are σX=3.02×10-19 cm2, σY=2.33×10-19 cm2, and σZ=2.68×10-19 cm2. The measured fluorescence lifetime τf is 64 µs, and the quantum efficiency η is 18.3%. In comparison with other Nd-doped laser crystals, the calculated parameters show that Nd:LCB crystal satisfies the fundamental spectral condition for laser emission.
