A linear cavity Nd:LNA laser pumped by a Ti:sapphire laser was investigated in a continuous wave, Q-switched and mode-locked regime. A parallel study utilizing a Nd:YAG crystal was also conducted utilizing the same optics and intracavity elements. The slope efficiencies obtained with a 5% output coupler in CW operation were 41 and 55% for Nd:LNS ([lambda] [approximately] 1.064 nm) respectively. Mode locking was achieved with a 360 MHz intracavity phase modulator and led to a relative improvement of the Nd:LNA versus the Nd:YAG device. In the Q-switched mode of operation with an intracavity acoustooptic modulator, the performance of the two lasers was almost identical. With 300 mW of absorbed pump power at [lambda] [approximately] 800 nm, peak powers [approximately]130 W were achieved in a 65 ns pulse with a 5% output coupler.
