| High resolution printing systems that utilize high power laser diode bars and digital mirror devices (DMD) require side-by-side stacking of illumination modules to stitching of the image from each module to form a longer total image width. An inline illumination optical system having a refractive prism and Total Internal Reflection (TIR) prism pair with an air gap along with a light guide transporting light beams at a compound angle to the prism pair eliminates the need for any axial rotation of the laser and light guide, and enables side-by-side module stacking. The illumination optical system includes an illumination module having a light source, the light guide, a DMD array and a Refractive TIR (RTIR) prism. The system also includes a DMD housing containing the DMD array and having a width within which the illumination module is confined to allow side-by-side stacking. | ||||||

| A pulse multiplier includes a beam splitter and one or more mirrors. The beam splitter receives a series of input laser pulses and directs part of the energy of each pulse into a ring cavity. After circulating around the ring cavity, part of the pulse energy leaves the ring cavity through the beam splitter and part of the energy is recirculated. By selecting the ring cavity optical path length, the repetition rate of an output series of laser pulses can be made to be a multiple of the input repetition rate. The relative energies of the output pulses can be controlled by choosing the transmission and reflection coefficients of the beam splitter. This pulse multiplier can inexpensively reduce the peak power per pulse while increasing the number of pulses per second with minimal total power loss. | ||||||

| The invention relates to a mirror arrangement for guiding a laser beam in a laser system having at least one first end mirror and one second end mirror, wherein said end mirrors define a resonator having an optical resonator axis, wherein the laser beam is guided into the resonator as an input laser beam and is guided out of the resonator again after multiple reflection at the first and second end mirrors as an output laser beam. The sequence of reflections at the first and second end mirror thereby determines a direction of rotation between the first and second end mirror, defined as an axis of rotation relative to the resonator axis, whereby a first beam path is defined and the laser beam circulates in a direction of rotation between the first and second end mirrors in the resonator defined as an axis of rotation relative to the resonator axis. The resonator is designed such that the direction of rotation is reversed at a reversing point and the laser beam in the resonator passes through at least partially in a direction of rotation opposite to the first beam path, whereby a second beam path is defined. | ||||||
