The spectral width of the polarizing effect of a coupling grating on a standard quarter-wave multilayer laser mirror can be increased by applying dual-duty-cycle gratings. As an example this is discussed considering the requirements to polarize a Yb:YAG thin-disk laser. By applying dual-duty-cycle gratings the spectral tolerance can be widened by a factor of two as compared to single-duty-cycle designs and at the same time achieve a high reflectivity and low losses for the oscillating polarized… CONTINUE READING
