Abstract:
1. A device for providing laser interlock comprising: a) a first optical source, a first beam splitter, a second optical source, a detector, an interlock control system, and a means for producing dangerous optical energy within a first protected output; b) said means for producing dangerous optical energy within a first protected output and said second optical source positioned with said first protected output; c) said first beam splitter optically connected to said first optical source, said detector, and said second optical source; d) said detector connected to said interlock control system; e) said second optical source configured to produce an optical energy in response to optical energy from said first optical source; f) the optical energy of said second optical source having a different wavelength, polarization, modulation or combination thereof from the optical energy of said first optical source; g) at least said second optical source within said first protected output; h) said interlock control system connected to said high-power optical source and configured to terminate optical energy emission from said means for producing dangerous optical energy upon the detection of optical energy at said detector from said second optical source below a predetermined detector threshold; i. an optical window connected to said second optical source and said means for producing dangerous optical energy; and whereby j. said second optical source is a coating on or is embedded on said optical window.
