ResumoWe present a semiconductor disk laser with a fundamental emission at 920 nm which is frequency-doubled utilizing a bismuth triborate nonlinear crystal. The generated blue emission at 460 nm is the most suitable wavelength for display applications. The device layer design and the applied resonator geometry are discussed. Experimental results reveal overall optical-to-optical conversion efficiencies of up to 41.5% for the fundamental and up to 14.5% for the second-harmonic emission.
