FIG. 3.

(Color online) Variation of on near-infrared fs pump power for angles of incidence (a) 45° and (b) 75°. The intensity diameter of the pump beam is approximately . This is equivalent to an excitation fluence (or energy density) normal to beam propagation of approximately at pump power. The dependence of the output power on the input power is close to quadratic.
