Abstract:
A signal detector and/or display system includes a bleachable dye medium whose transparency to optical signals is nonlinearly related to the intensities of coincident signals transmitted through the medium. A pulse of picosecond width is detected and the pulse width measured by causing the pulse to overlap itself within the medium. A complex signal is displayed by sampling the signal with a picosecond pulse within the medium.
Abstract:
A laser device for operation in the X-ray region comprises a resonator of three-dimensional polygonal shape having Bragg angle reflections at the apices of the polygon. The laser is pumped by removing electrons from the innermost shelfs of atoms of the active medium in synchronism with generation of X-rays traveling in the active medium. Pumping energy is achieved by collisions of relativistic particles and laser beams or by laser beam impingement on X-ray-emitting material.
Abstract:
Lasing at ultraviolet and other wavelengths is achieved in a two-photon laser employing organic liquid mediums such as benzene solutions of 9, 10-dibromoanthracene, 9-methylanthracene and 9, 10-dimethylanthracene.
