Granted: 2011-05-24
Abstract: Isolated tumoricidal herpetic viruses, in particular neurotrophic herpes viruses, T-lymphotrophic viruses, and B-lymphotrophic viruses, which are avirulent and capable of selectively replicating in and destroying neoplastic cells, and pharmaceutical compositions, vaccines, and methods of destroying neoplastic cells employing the isolated tumoricidal herpetic viruses are described. A method of isolating tumoricidal herpetic viruses by sequentially passaging attenuated, avirulent herpetic viruses on neoplastic cells which fail to support replication of the herpetic viruses and isolating the viruses which grow on the neoplastic cells is also described. Herpes simplex virus mutants having a genome from which the .gamma.34.5 genes have been deleted and which require at least one additional mutation to produce a non-neurovirulent herpes simplex virus which selectively replicates in and destroys neoplastic cells are also described.

Abstract: A monolithic solid state laser structure is used to construct erbium lasers that are insensitive to external pressure changes and vibrations, and have improved cooling of the gain medium (20) and reduced thermal lensing effect.  In the monolithic laser structure, the gain medium (20) is separated from an optically transmissive plate (24) on one side and a wave plate (21) on the other side by spacers to form narrow air gaps (31 and 33) which provide effective cooling of the gain medium (20) and reduced the thermal lensing effect. Such an arrangement is further combined with a pressure-insensitive brewster polarizer such as a solid brewster polarizer (42 and 46), or a pressure-sealed brewster plate (249), to form a pressure-insensitive laser cavity. The wave plate (2') cooperates with the brewster polarizer (42 and 46) to select the wavelength of the solid state laser.
