High power and high profit saturation diode pumping laser expedient and diode array pumping device

摘要

(57) Abstract Optical means in order the diode pumping solid state laser in order to make the high aspect ratio beam cause, the diode array mount (3) diode pumping array above has (1) and smooth strength profile and image formation to do the pump light beam substantially in asymmetric spot are included. Laser medium (4) the pumping it does the said pump light beam. Pump and rejingumodo have powerful asymmetry together. When it combines with the selection whose laser medium (4) is correct, as a result, you can obtain high power laser efficiency. Can the axis of the pump light beam, adjust the surface or the direction which is demarcated vis-a-vis the installation frame (111) of the diode array pumping device (103) with simple adjustment expedient (110). The said adjustment expedient (110) compensates small allowance diode array (1) and/or at least one optical element (2) vis-a-vis installation. The said adjustment expedient includes one wedged window (127) at least. For this adjustment, as for the axis of the light beam it is inside the surface which is demarcated vis-a-vis the installation frame (111) of the pumping device (103). Therefore, as for the diode array pumping device (103) of the laser each further adjustment losing, it is possible to replace.
