Abstract

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 (M² ≥ 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.
