Abstract: PURPOSE:To provide a short wavelength laser light source equipment capable of oscillating short wavelength laser light with high efficiency. CONSTITUTION:An optical material in doped with Tm ions and Tb ions. As to the Tm ions, absorption transistion 203 to the <3>H4 level is caused by a pumping light of 670-810nm. As to the Tm ions at the <3>H4. level, absorption transition 204A to the <1>D2 level is caused by a pumping light of 640-650nm. Energy of the Tm ions which are subjected to luminous transition or nonluminous transition from the <3>H4 level to the <3>F4 level is transferred to the Tb ions by absorption transition 204B and luminous transition 206 or energy transfer 207. Thereby the Tb ions are excited up to the <5>D4 level. The energy at the <5>D4 level which the Tb ions have is subjected to energy transfer 208 to the Tm ions having energy at the <3>H4 level. Thereby the Tm ions are excited up to the <1>D2 level. The population inversion state is formed between the <1>D2 level and the <3>F4 level of the Tm ions.

Title: Diagonally and perpendicularly oriented liquid crystal cell and production thereof
Inventor: SEKI HIDEHIRO
IPC: G02F1/1337
Filed: 1990-01-30
Abstract: PURPOSE:To obtain the orientation uniform over a large area by rubbing a substrate in a suitable direction and treating the substrate with a perpendicular orientation treating agent, thereby diagonally and perpendicularly orienting liquid crystal molecules. CONSTITUTION:Grooves are generated on the glass substrate 1 by rubbing and asymmetrical saw tooth-like changes are generated when orientation anisotropy is imparted to the substrate by rubbing. The perpendicular orientation treating agent is applied on this rubbed glass substrate 1. A DMOAP, i.e. an org. silane coupling agent having a long-chain alkyl group is used for the perpendicular orientation treating agent in this case. The diagonal and perpendicular orientation of the liquid crystal molecules is, therefore, possible and the occurrence of a change in a vapor deposition angle by the position of the substrate like in the case of use of a diagonal vapor deposition method in particular does not arise. The dependency of the display contrast on the position of the substrate does not arise either. The orientation that the liquid crystal molecules are uniformized at the time of voltage impression is obtd. in this way even if a liquid crystal display of a large screen is formed.
