Abstract
Systems and methods are disclosed for selectively passing or blocking laser electromagnetic energy. A laser system comprises a shutter, whereby when the shutter is rotated one or more open areas of the shutter and one or more solid areas of the shutter are alternately positioned in a path of electromagnetic radiation emitted by the laser. The shutter may operate in different modes, including allowing all laser pulses to pass through in whole or in part, blocking all laser pulses from passing through, and alternately allowing and blocking laser pulses. In some embodiments, the shutter is controlled to allow only a part of each selected laser pulse to pass through. A laser system comprises a waveplate rotatable into different positions corresponding to different operating modes. The different operating modes may include allowing part and blocking part of the laser electromagnetic radiation.
