The realization of the specified values in cw-mode (continuous wave mode) implies a suitable mounting technology with a thermal resistance of Rth < 0.3 K/W. The operating emission wavelength depends on the operating mode (cw or pulsed, ambient temperature, thermal resistance Rth) and is in general higher than the specified center pulse wavelength λpulse. All characteristics obtained in the respective operating mode may differ from the characteristics specified herein. 2) Specified at the typical optical output power Pop, typ. 3) Parameter strongly depends on bar mounting.  Typical values for cw-operation of bars mounted with hard solder (Rth = 0.3 K/W, TA = 20°C). 4) Full width at 95% power content.
