International ClassesA61F 9/007 (20060101)A61F 9/008 (20060101) Foreign Application Priority Data1983-10-29 DEAbstractA pulsed laser for medical application and particularly for ophthalmological treatment is described.The laser beam pulse has a clearly defined polarization plane. By rotating a polarization splitter cube, it is possible to regulate the energy of the laser beam pulse.Following each rotation of the polarization splitter cube, and prior to the following treatment pulse, a control system releases a test pulse. The energy of the test pulse is measured while the shutter closes the treatment beam path.According to a preferred embodiment, the laser is a neodymium-YAG laser.Field of SearchPolarization | |
