Abstract
A new, to our knowledge, neodymium-doped lanthanum calcium borate crystal 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 are and The radiative lifetime is 349 µs. The absorption band at 800 nm has a FWHM of 12 nm. The absorption cross section is and the emission cross sections at 1070 nm are and The measured fluorescence lifetime 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.
