摘要： The invention relates to an optically pumped ultrashort pulse microchip laser for generating a laser emission having femto- or picosecond pulses, comprising a substrate, an amplifying laser medium, a first resonator mirror that is at least partially transparent to optical pump radiation, and in particular a saturable absorber structure. The laser medium is applied to the resonator mirror and the substrate and subsequently reduced from the original material thickness to a thickness of less than 200 μm. In order to achieve satisfactory power absorption despite said low thickness, the optical pump radiation is coupled into the laser medium such that resonance occurs for the laser emission and excess intensity increases occur for the pump radiation.

摘要： A diode pumped solid state laser for producing a high aspect ratio beam comprises a diode pumping array (1) on a diode array mount (3) and optical means for imaging a pump light beam onto a substantially asymmetrical spot with a smooth intensity profile. The pump light beam is pumping a laser medium (4). Both the pump and the lasing mode have strong asymmetries. In combination with the right choice of laser medium (4), this results in high power laser performance. The axis of the pump light beam is adjustable by a simple adjusting means (110) to a defined plane or direction relative to a mounting frame (111) of a diode array pumping device (103). The adjusting means (110) compensates small tolerances on mounting of the diode array (1) and/or at least one optical element (2). The adjusting means include at least one wedged window (127). Because of this adjustment the axis of the light beam lies in a defined plane relative to the mounting frame (111) of the pumping device (103). Therefore the diode array pumping device (103) of a laser is replaceable without any further adjustment.

摘要： The use of reflecting surfaces that are inclined towards one another enables the multiple reflection of a beam path to be achieved in a laser structure. This permits the realization of compact laser assemblies. The introduction of beam-influencing media between the reflective surfaces or the configuration of said reflective surfaces from or using media of this type allows the use of the multiple reflection for influencing parameters of the radiation or radiation field.
