Abstract:
1. A laser safety system comprising: at least one gain module for absorbing at least one input laser beam to store power within said at least one gain module, and for at least partially discharging said stored power through at least one output laser beam; at least one input device for transmitting said at least one input laser beam onto said at least one gain module; at least one output device for transmitting said at least one output laser beam off of said at least one gain module in order to at least partially discharge said stored power from said at least one gain module through said at least one output laser beam; and at least one computer comprising at least one database and at least one power reducing routine, the at least one database configured to store an input power level of the at least one input laser beam, to store a discharge power level of the at least partially discharged stored power discharged through said at least one output laser beam, and to store a power safety differential limit, the at least one power reducing routine comprising at least one algorithm configured to calculate a power differential by subtracting the discharge power level from the input power level, and to at least one of reduce power to and shut down the at least one input device if the calculated power differential exceeds the power safety differential limit.
