The semiconductor disk laser (SDL) takes advantage of the potential for band-gap engineering in semiconductor multilayers to give a wavelength flexible laser source; the free-space cavity not only gives the freedom of design to achieve good beam quality and power scaling, but also to insert wavelength control elements into the cavity for spectral narrowing and tuning, and for second harmonic generation (SHG). Thermal modelling using finite element analysis (FEA) was used to compare the different thermal management techniques used to dissipate the heat generated by the optical pumping process, which ultimately limits the output power achievable in these devices: an intracavity diamond heatspreader was chosen as the most appropriate technique where wavelength diversity is required.
