Problems solved by technology
[0003] In the multi-optical parametric oscillation process based on Nd:MgO:APLN, when the energy of the injected fundamental frequency light is too large, the energy field imbalance between the pump light and the parametric light will cause inverse conversion, which will lead to a decrease in conversion efficiency, deterioration of beam quality and Spectrum broadening, gain imbalance between multiple groups of parameter oscillations can easily lead to excessive output power difference

Description
technical field [0001] The invention relates to the field of solid-state lasers, in particular to a multi-wavelength mid-infrared laser energy ratio control amplifier based on Nd:MgO:APLN crystals. Background technique [0002] Aperiodically poled superlattice crystals can provide multiple reciprocal lattice vectors to compensate for multiple sets of phase mismatches. In the multi-optical parametric oscillator based on superlattice crystals, the pump light can be converted into multiple sets of parametric light at the same time to realize multi-wavelength laser output with the same period or across periods. MgO-doped LiNbO 3 Crystals are made into non-periodically polarized MgO:APLN crystals because of their good optical and electrical properties, and are often used for multi-optical parametric oscillation. MgO:APLN Crystal Doped with Gain Ion Nd 3+ The formation of Nd:MgO:APLN crystal can not only compensate the phase mismatch and realize multi-optical parametric oscilla...
