PCT No. PCT/DE84/00225 Sec. 371 Date Jun. 27, 1985 Sec. 102(e) Date Jun. 27, 1985 PCT Filed Oct. 29, 1984 PCT Pub. No. WO85/01869 PCT Pub. Date May 9, 1985.A 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.
