Abstract
A novel nonlinear-optical laser crystal, Yb3+:YAl3(BO3)4, has been grown with good optical quality by the method of high temperature flux. Room and low temperature absorption and fluorescence spectra have been measured and spectral parameters have been calculated. The ground-state energy-level splitting is 581cm−1. The emission lifetime is 0.68ms and the peak emission cross section is over 1.0×l0−20cm2. The data show that this crystal has potential as an efficient self-doubled laser operating in the green.
