High-Gain Laser Diode Array Side Pumped Nd: Glass Rod Amplifier

Abstract:

With the optimized side pumped module structure, three laser diode arrays rotating symmetrically pump the Nd: Glass rod. The size of the Nd: Glass rod is Φ2 mm×75mm, with the doping concentration of 4at%. The surface of both ends of the rod coated with antireflection film at 1053nm, the rod was tilted 1.5°in order to eliminate the oscillation of amplified spontaneous emission (ASE). The seed, with energy 10μJ, operating frequency of 1Hz, pulse width 3ns, output wavelength 1053nm, through the Nd: Glass amplifiers reaches 70 times stable high-gain when the pumping power is 8.2kW and the pulse-width is 400μs. Meanwhile, the fluorescence distribution of the amplifier is homogeneous.
