Investigation of diode-pump absorption efficiency and thermo-optical effects in a high-power Yb : KGW laser

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 t...
