摘要： Optical recording media for storing information on which bits are formed by applying radiant energy to a polydiacetylene thin film supported by a substrate, so that the main chain structure of the polydiacetylene is transformed into another form or forms. The optical recording media has the advantages of allowing high-speed recording both with small amounts of energy for recording and with high recording density.

摘要： An optical control system and method comprised of obtaining optical bistability by radiating a crystal with both the exciton energy level and the excitonic molecule energy level as the optical excition energy level, with a laser beam having energy less than (Em/2-.gamma.), in which Em is the excitonic molecular energy level, an .gamma. is the half-amplitude level of absorption spectrum of two-photon resonance. The advantage of optical bistability is that high speed switching of an order of pico-seconds is possible due to the coherent non-linear response, and that switch-on and switch-off energy required is less than pico-Joule.

摘要： A transition metal doped spinel type MgAl2O4 fluorescent material capable of laser oscillation and a laser apparatus using the same. It is made from a mixed raw material of an Al raw material and a Mg raw material added thereto in an amount together with a transition metal raw material so that the amount of Mg exceeds that of Al by a few percents in terms of molar ratio, by shaping the mixed raw material under pressure to form a source material rod, and single-crystallizing the source material rod in a selected gaseous atmosphere by floating zone melting. The doping amount of Ti is such that in composition formula MgAl2-xTixO4 it lies in a range: 0.003≦x≦0.01. The doping amount of Mn is such that in composition formula Mg1-xMnxAlO4 it lies in a range: 0.003≦x≦0.01.
