Diff,r&ctive optical elements for CO2 laser beam diagnostics
نویسندگان
چکیده
In laser machining great interest has been shown in diagnostic tools for on-line testing and correcting. We present here beam sampling mirrors, which are basically shallow gratings, and which can be applied to give an accurate sample of the original beam without deteriorating it. The method compares favourably with other techniques for beam diagnostics. First results using these elements are presented.

متن کاملUsing of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser
Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...
متن کاملDiagnostics of Laser Initiated Plasma Channels for Ion Beam Transport
Laser initiated, free standing discharge channels offer many attractive advantages for the transport and focusing of intense ion beams [1, 2]. Discharge plasmas can neutralize both current and space charge of such beams, while the azimuthal magnetic field provides strong focusing all the way through the channel. Experiments at GSI have produced 50 cm long stable plasma channels with peak curren...
