  • Patent number: 10625418
    Abstract: A control system, a controller, a control method and a recording medium capable of preventing damage to a cable occurring during an operation under control of a scara robot are provided. A control system includes a scara robot 300 and a controller configured to control the scara robot 300. The controller includes an acquisition unit configured to acquire a target position of a control object in the scara robot 300 and a decision unit configured to decide a rotational direction of an operation tool 332 so that a cable 333 does not collide with a component of the scara robot 300 when the control object moves to the target position.

  • Patent number: 10625417
    Abstract: A control system including a selective compliance assembly robot arm (SCARA) robot is provided. The SCARA robot includes a first arm configured to be rotatable around a first rotation shaft, a second arm configured to be rotatable around a second rotation shaft arranged parallel to the first rotation shaft and provided on the first arm, and a main shaft configured to be drivable in a direction parallel to the second rotation shaft and provided on the second arm. The control system includes a setting unit providing a user interface for receiving a setting of a two-dimensional operation prohibition region with respect to a point of interest on the SCARA robot. The operation prohibition region corresponds to an area on a plane orthogonal to the main shaft. The control system includes an extension unit two-dimensionally extending the operation prohibition region through an extension in a direction of the main shaft.

  • Patent number: 6873454
    Abstract: A hybrid chirped pulse amplification system wherein a short-pulse oscillator generates an oscillator pulse. The oscillator pulse is stretched to produce a stretched oscillator seed pulse. A pump laser generates a pump laser pulse. The stretched oscillator seed pulse and the pump laser pulse are directed into an optical parametric amplifier producing an optical parametric amplifier output amplified signal pulse and an optical parametric amplifier output unconverted pump pulse. The optical parametric amplifier output amplified signal pulse and the optical parametric amplifier output laser pulse are directed into a laser amplifier producing a laser amplifier output pulse. The laser amplifier output pulse is compressed to produce a recompressed hybrid chirped pulse amplification pulse.

  • Patent number: 6870664
    Abstract: A system provides an input pump pulse and a signal pulse. A first dichroic beamsplitter is highly reflective for the input signal pulse and highly transmissive for the input pump pulse. A first optical parametric amplifier nonlinear crystal transfers part of the energy from the input pump pulse to the input signal pulse resulting in a first amplified signal pulse and a first depleted pump pulse. A second dichroic beamsplitter is highly reflective for the first amplified signal pulse and highly transmissive for the first depleted pump pulse. A second optical parametric amplifier nonlinear crystal transfers part of the energy from the first depleted pump pulse to the first amplified signal pulse resulting in a second amplified signal pulse and a second depleted pump pulse. A third dichroic beamsplitter receives the second amplified signal pulse and the second depleted pump pulse. The second depleted pump pulse is discarded.

  • Patent number: 6791743
    Abstract: A first pump pulse and a signal pulse are injected into a first optical parametric amplifier. This produces a first amplified signal pulse. At least one additional pump pulse and the first amplified signal pulse are injected into at least one additional optical parametric amplifier producing an increased power coherent optical pulse.
