Abstract (en)

[origin: WO2013113306A1] The invention relates to a CO2 laser which allows for rapid power modulation, particularly highly efficient Q-switching. The key concept is the sub-division of the resonator into a high-power branch, containing inter alia the active medium (1), and a low-power feedback branch (14), in which the power-sensitive beam-shaping elements, particularly the modulators, are arranged. This is made possible by a suitable arrangement of a polarisation beam splitter (5) and a lambda/4-phase shifter (2). The free adjustability of an angle phi between said two components permits the extremely flexible realisation of various operating modes, particularly optimisation of the feedback degree during pulse generation.
