摘要： A system and method for high power parametric amplification based on performing amplification in a frequency domain after time domain pulses are optically Fourier transformed, to overcome bandwidth limitations. In a nutshell, a first optical Fourier transformation of a seed spectrum is performed and parametric amplification is carried out in this spatially dispersed frequency plane. As a consequence, individual parts of the spectrum can be amplified using an optical amplification medium comprising a series of optical amplification units, such as different narrowband crystals, placed one next to each other. Each crystal is tuned independently to optimize its corresponding spectral slice. A second optical Fourier transformation recovers the time domain laser pulses. This method enables scalability of amplified bandwidth and pulse energy at the same time.

摘要： A system is disclosed for detecting a signal field from a sample volume. The system includes a source system and an optical fiber system. The source system provides a first electromagnetic field at a first frequency and a second electromagnetic field at a second frequency that is different from the first frequency. The optical fiber system includes at least one optical fiber for guiding the first and second electromagnetic fields to the sample volume to generate coherent radiation characteristic of molecular vibrations by non-linear interaction of the first and second fields with the sample volume. The optical fiber system also receives the signal field resulting from the coherent radiation, and guides the signal field to a detector.
