Laser Generation Apparatus and Sources Using the Same
This technology is an apparatus that uses a chirped pulse laser of wavelength λ1 combined with its second harmonic at λ2 to achieve a sum-frequency λ3. The chirp rate can be determined on a material basis and the process holds for λ2 = λ1/2, λ3 = λ1/3. This is achieved using nonlinear materials and the...

Interleaved Multi-Pass Optical Amplifier
This invention is a multi-pass master oscillator power amplifier (MOPA). The technology is an optical amplifier, such as a laser amplifier, that has been configured so the signal cycles through the gain media multiple times. The goal of this is to better saturate the available power from the gain but also greatly decrease the amplified spontaneous emission...
