The first demonstration of a pulsed Nd:YCOB laser at 1060 nm is reported, with results for both gain switching and Qswitching
presented. Active Q-switching is achieved using the spinning disc technique pulses of 50 ns duration with
pulse energies up to 0.6 mJ are obtained. Optimisation is performed for both pulse energy and slope efficiency of the
laser. A Q-switched slope efficiency of 56% is achieved.
