Abstract

A high brightness diode laser module based on single emitters is presented, offering a maximum output power of 15.5 W at 35 Hz repetition rate and 100 μs pulse length. While the presented module (6xx nm) is designed and used for longitudinally pumping an alexandrite laser for atmospheric measurements, the conceptual design is suited for the whole range of diode laser wavelengths from UV to NIR as well as for fiber coupling. The beam propagation factor has been measured to be M2 = 34. To the authors' knowledge this is the highest brilliance ever reported at the specific wavelength.
