✦ Synopsis

A COz TEA laser has been used to photolyze dilute samples of various aIky1 halides in helium. The mechanism of the high intensity infrared photolysis of these moiecules involves the decomposition of moiecules into molecular or radical fragments. The reaction pathway is always dissociation into the lowest thermal dissociation channel(s) of the molecule photolyzed. Products from the initial process are also photo-dissociated by the laser pulse and their decomposition pathways are similarly governed. The molecules being photolyzed are not thermally equihbrated with the bath or with each other and the molecular-specific nature of the laser excitation is demonstrated.

A precise cochleostomy is a crucial step in cochlear implantation, particularly if residual hearing is to be preserved. A contactless ablation of the promontory bone by a pulsed CO 2 laser system seems to be a promising approach. The bone is removed by a scan head controlled laser beam in sequential
