  • Device and method for adjusting laser pulse width using laser-induced plasma shutter
    Patent number: 11855405
    Abstract: The present disclosure relates to a device and a method for adjusting a pulse width of a laser beam by using the plasma generated by being induced from laser as a shutter, and more particularly, to a device and a method for adjusting a laser pulse width, which can precisely and quickly adjust the laser pulse width by dividing the laser generated from a laser light source into a target pulse and a shutter pulse; converting the optical path of the divided laser; and chopping the target pulse by using the plasma induced from the shutter pulse as an optical shutter in a cell having adjustable internal pressure.
