Design and Development of a High-Performance LED-Side-Pumped Nd∶YAG Rod Laser
文献摘要：
We present a design and development of a high-performance light-emitting diode(LED)-side-pumped Nd∶YAG rod laser with strong pulse energy,high efficiency,and consistency,very good beam quality,and high uniform pumping intensity in the active area which reduces the effects of thermal gradient significantly.A five-dimensional 810 nm LED array with a full width of 30 nm at half maximum was intended to achieve high coupling efficiency by putting the LED array as close as possible to the side of the Nd∶YAG laser rod for overcoming the large pumped divergence.Under 2.25 J pump energy,maximum single pulse energy of 35.86 mJ with duration of 1.24 μs at 1063.68 nm was obtained,equivalent to optical efficiency of 1.59％and a slope efficiency of 2.53％.The laser was set to repeat at a rate of 10 Hz with a beam quality factor of M2x=2.94 and M2y=3.35,as well as with the output power stability of＜4.1％(root mean square)and＜7.3％(peak to peak).To the best of our ability,this is the highest performance for an LED-side-pumped Nd∶YAG rod laser oscillator with a 10-mJ-level output ever reported.
