Beschreibungen/Notizen

• Diode-pump absorption is experimentally studied in a high-power (Yb : KGW) laser in the presence and absence of lasing. The maximum absorption efficiency in the cw regime exceeds 77 % which is by a factor of 1.4 greater than the maximum absorption efficiency in the absence of lasing. The powers of thermo-optical lenses induced in laser crystals during lasing are measured. A strong dependence of the lens power and aberrations on the orientation of laser crystals relative to the propagation direction and polarisation is confirmed.
