| 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. | ||||||

| PURPOSE:To obtain an optimum construction for the added inductance, by obtaining a stricter equivalent circuit as a coaxial line constituting the added inductance to cancell the reactance of a varactor. CONSTITUTION:A signal circuit of a parametric amplifier comparatively low in the signal frequency is constituted with a coaxial line 1, and consists of added inductance section 3, 1/4 wavelength transformer 4 and input and output 5. Although the added inductance 3 has recesses such as an idler choke 6 and a pump waveguide 8, since the recesses are very small, the equivalent circuit can be considered as a circuit between A-A' and B-B' by taking the circuit as a coaxial line. From this equivalent circuit, the shape or the band to minimize the resistance (r), that is, to minimize the noise temperature can be obtained. | ||||||

| PURPOSE:To avoid the deterioration of noise temperature at the upper end of band, by providing gain compensation line between the signal main resonator and the signal subresonator. CONSTITUTION:The 1/4 wave length lines 5 and 6 constitute the impedance transformer and the subresonator, and the gain compensation line 7 has the characteristics impedance almost the same as negative resistance at the series resonance point of the main resonator. The shortest line length of the line 7 is 1/4 wave length or less, and the circuit at diode side from the B-B' of the line 7 constitutes the parallel resonant circuit. By selecting the characteristics impedances Z01 and Z02 of the lines 5 and 6 to obtain the Q required for flat gain, the gain characteristics can be made flat to reduce the deterioration due to noise temperature at the upper end of band. | ||||||

| PURPOSE:To establish the amplifier of broad band which is small in size, less in constituent components and less in the circuit loss. CONSTITUTION:The amplifier consists of the varactor diode 1, idler resonator 2, idler choke 3, coaxial line for signal resonation 4, 1/4 wave length line two stages 8,9. The line characteristic impedance of the broad band circuits 8 and 9 are taken as Z1 and Z2, and the line length is taken as 1/4 wave length at the center frequency of signal. The reactance of the idler resonance circuit and the negative resistance of the varactor diode are respectively shown as C1,L1-C2,-L2, and -RA. The input impedance Zin at which the circuits 4 and 2 are respectively in resonance at the signal center frequency is Zin=(Z1/Z2)<2>X-RA. The impedance is transformed to 1:Z2/Z1 with the two stages of line by Z1 and Z2, and the two stage line is in parallel resonance and becomes a subresonator. When keeping Z2:Z1 constant and changing the absolute value, the adjustment of Q of the subresonator can be made with constant transformation ratio, and the transformation ratio can be varied by changing Z2:Z1. | ||||||
