High Quality Content by WIKIPEDIA articles! X-ray laser is a device that uses stimulated emission to generate or amplify the electromagnetic radiation in the near X-ray or extreme ultraviolet region, usually in the order of several nanometer or tens of nm. Because of high gain in the medium, short upper state lifetime (1 - 100 ps) and problems associated with construction of X-ray mirrors, the X-ray laser usually operates without any resonator. The emitted radiation based on amplified spontaneous emission has relatively low spatial coherence. The line is mostly Doppler broadened (which depends...
High Quality Content by WIKIPEDIA articles! X-ray laser is a device that uses stimulated emission to generate or amplify the electromagnetic radiation in the near X-ray or extreme ultraviolet region, usually in the order of several nanometer or tens of nm. Because of high gain in the medium, short upper state lifetime (1 - 100 ps) and problems associated with construction of X-ray mirrors, the X-ray laser usually operates without any resonator. The emitted radiation based on amplified spontaneous emission has relatively low spatial coherence. The line is mostly Doppler broadened (which depends on the ion temperature). As the common laser transitions between electronic or vibrational states correspond to energies up to 10 eV, a different active medium is needed.
