An installation formed of several independent groups is proposed to demolish structures such as buildings, bridges, materials, etc., in particular eliminating any risk of accidental firing. Each group comprises a control unit (10) with several outputs (18) including at least one laser source (16), pyrotechnic initiators (12) with optical control, and optical fibers (14) connecting the outputs (18) of the control unit (10) to the initiators (12). Laser sources (16) may be either laser diodes, or sources with a pumped solid rod operating in relaxed mode.

[What is claimed is:] [1.]at least two independent groups of demolition installation components, each including:a control unit including several outputs, a single laser source for each of said several outputs, and at least one control switch for each of said laser sources, said laser sources being a pumped solid rod operating in a relaxed mode such that closure of said control switches will cause said laser sources to emit a first laser beam for at least one of said several outputs;optically controlled pyrotechnic initiators placed at determined locations in a structure to be demolished;optical fibers connecting each of said pyrotechnic initiators to one of said several outputs of said control unit;a first optical divider coupler receiving a primary optical input, in a form of said first laser beam, emitted by said laser sources;a secondary optical input directing a second laser beam to penetrate said control unit; andfirst feedback means configured to direct said second laser beam from said secondary optical input to said primary optical input of said first optical divider coupler for said control unit; andan additional laser source common to all of said at least two independent groups, said additional laser source emitting said second laser beam to said secondary optical input.
