Abstract
Dual-wavelength waveguide lasing at 1064 and corresponding to the and Nd transitions has been demonstrated in a femtosecond-laser-inscribed Nd: channel waveguide. Under optical pumping, the obtained laser thresholds at 1064 and were 180 and , respectively. The laser slope efficiencies at 1064 and were found to be 15.6% and 1.7%, respectively.
