A Proposed Laser Incident Threshold Level

Document #:
Document type:
T - Technical notes
Other Versions:
This document presents the rationale and assumptions used to justify the proposed increase of the laser incident threshold power level. The proposed change is that the incident threshold power level be increased from 100 μW to mW for all laser wavelengths within the LIGO Laboratory. This limit is derived from the current ANSI Z136.12007 American National Standard for Safe Use of Lasers. The ANSI standard is a factor of 10 below any known damage threshold.
