Radiation to coherent light converter
We have developed a radiation to coherent light converter with a monolithically integrated semiconductor chip that consists of a chromium-doped GaAs photoconductor detector and a GaAlAs laser diode. When irradiated, the electric pulse generated by the photoconductor detector modulates the laser diode, which has been biased above the lasing threshold, thus converting a radiation pulse to an electric pulse and then to a light pulse. The laser pulse is then transmitted to a fast recorder through a high bandwidth optical fiber. In the absence of a single-step x-ray pumped laser, our converter appears to be the first integrated device that can efficiently convert x-ray flux into coherent light. This device has been tested successfully with the 50 ps electron beams of 17 MeV linear accelerator and with 50 ns x-ray pulses from a Z-pinch plasma source.
