Abstract

We demonstrate a Fourier domain mode locked (FDML) laser centered at 1190 nm with 2×410 kHz sweep repetition rate, a sweeping range of 100 nm and 2.5 mW output power. The laser is based on a quantum dot-semiconductor optical amplifier with small linewidth enhancement factor. The laser could be used as a probe laser in stimulated Raman scattering microscopy and it may be attractive for optical coherence tomography due to low water absorption and the spectral signature of lipids around 1200nm. Moreover, it is ideal to close the gap between FDML lasers at 1064 nm and 1300 nm. Combining these three lasers can enable ultrawideband sweeping to improve the axial OCT resolution down to 2 μm.

N2 - FDML lasers already exist at 1064, 1300 and 1550 nm [1], they typically provide a bandwidth over 100 nm with a typical resulting axial resolution around 6 µm. A combination of a 1064 nm and a 1300 nm FDML laser would enhance the axial resolution due to a wider bandwidth of about 300 nm.
