An Infrared Picosecond Optical Parametric Oscillator for Polymer Ablation
The development of an infrared optical parametric oscillator based on Magnesium Oxide doped Periodically Poled Lithium Niobate (MgO:PPLN) is described. The OPO is synchronously pumped by a high average power, picosecond, Nd:YVO4 mode-locked laser operating at 1064nm. The OPO generates signal and idler radiation at wavelengths centered at 1550nm and 3.4µm respectively. The OPO is singly resonant at the the signal wavelength. The multiple QPM grating periods and temperature control imposed upon...[Show more]
