Indirect exciton superradiant recombination in diamond: Theory and the perspectives of observation

A method of generation of powerful pulses of ultraviolet and soft X-ray coherent radiation is considered. It consists in employing superradiant indirect exciton recombination in large enough high quality diamond samples. The theory of this transient process is developed and its dynamics is simulated. In result it is shown that this method may probably provide the generation of picosecond pulses of coherent electromagnetic field with peak powers larger than 30 W at wavelength 235 nm. -- Highlights: ► The method of pulsed generation of ultraviolet coherent radiation is considered. ► The method is based on superradiant indirect exciton recombination in diamond. ► The theory of this process is developed and its numerical simulation is conducted. ► The picosecond pulse peak power is larger than 30 W at 235 nm
