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 and greatly decrease the amplified spontaneous emission...

Chance-Constrained Optimization for Treatment of Prostate and Other Cancers in Intensity-Modulated Proton Therapy

The quality of IMPT treatment plans may be drastically diminished by uncertainties such as proton range and patient setup errors. If these uncertainties are not figured into treatment planning, the dose distribution that the patient receives may not be the same as the planned dose distribution. New treatment plans, which include optimized software/programming,...
