  • Solid state microlaser
    Patent number: 4860304
    Abstract: A solid state gain medium is disposed between two mirrors to form a resonant cavity, the cavity length selected so that the gain bandwidth of the gain medium is less than the frequency separation of the cavity modes. By selecting this cavity length, only a single longitudinal mode will oscillate when the laser operates in a single transverse mode. The microlaser is optically pumped by any appropriate source such as a semiconductor injection laser or laser array. Suitable gain media are Nd:YAG and Nd pentaphosphate.

  • 3-Amino-tetrahydrocarbazoles
    Patent number: 4257952
    Abstract: 3-(Substituted-amino)-1,2,3,4-tetrahydrocarbazoles are prepared by reacting appropriate 4-substituted-aminocyclohexanones with a phenylhydrazine, by reacting a 3-(sulfonyloxy)-1,2,3,4-tetrahydrocarbazole with an appropriate substituted amine, or by reduction of an appropriate 3-(acylamino)-1,2,3,4-tetrahydrocarbazole. The 3-(substituted-amino)-1,2,3,4-tetrahydrocarbazoles of this invention have analgetic and psychotropic activities. Moreover, certain of these compounds also have antihistaminic activity.
