  • Laser pulse generation method and apparatus
    Patent number: 9089927
    Abstract: A method and apparatus of generating a laser pulse of a desired energy and micro-machining a substrate using the laser pulse. A beam of light is provided from a laser source. The beam is directed via a modulator to produce an output laser pulse with a portion of the laser pulse being used to determine the energy of the laser pulse. The modulator is controlled so as to switch off the output laser pulse when the determined energy of the output laser pulse reaches a threshold value. The output laser pulse is steered to a substrate for micro-machining.

  • Fast-axis collimator array
    Patent number: 8570657
    Abstract: A micro-optical element for use with an edge-emitting laser diode bar stack, the element comprising a plurality of spaced apart fast-axis collimators formed as a monolithic array, wherein the spacing between the collimators in the fast-axis varies across the micro-optic element. A method of manufacturing a micro-optical element for use with a laser diode bar stack, using a wavelength stabilized CO2 laser is also described.
