We demonstrate our latest work towards a red-emitting semiconductor membrane external-
cavity surface-emitting laser (MECSEL) for applications in OCT. This light source technology
employs both a near-diffraction limited beam profile (M 2≥ 1.05) and a broad tuning range
at tailorable emission wavelength. Due to their potential for mass production, combined with
the usage of broadly available CMOS-sensors as detector units, OCT imaging device costs
can be reduced to a significant amount, while delivering state-of-the-art image quality.
