PhD Project: Broadband gain blocks for amplified swept source

In optically pumped membrane external-cavity surface emitting lasers (MECSELs), power scalability in to the WATT level is given while providing a high beam quality (M² ≈1.0). Also, yet uncovered wavelength ranges can be reached with this approach. The gain can be designed via choosing a constellation of different quantum well or quantum dot layers to cover a wide spectral range. Modern Fourier-domain OCT needs broadband coherent light sources with fast sweepable emission. MECSELs could provide these demands.
