Abstract :
We demonstrate an efficient diode-pumped Nd:CBN-28 ferroelectric crystal laser for the first time. The maximum output power of 0.536 W is achieved with a slope efficiency as high as 27.7%, which is higher than that in the Nd:SBN ferroelectric crystal laser. The self-frequency doubling and self-sum-frequency processes are obtained simultaneously under intracavity conditions in the diode pumped Nd:CBN-28 laser. These processes show the ability of the Nd:CBN-28 crystal as a nonlinear optical multi-frequency converter without any angle or temperature tuning.
