Tunable Laser with Subharmonic Spectral Mode-Coupling
Tunable lasers are used in a wide range of applications like profilometry, laser spectroscopy, and optical sensors for measuring pressure and temperature and optical coherence tomography. A powerful concept enabling ultra-high tuning rates is e.g. Fourier Domain Locking (FDML). Lasers using FDML, however, need glass fibres with a length of several kilometres. The presented tunable laser with subharmonic modecoupling uses a shorter optical resonator which allows to reduce the production costs significantly, while still reaching several hundred thousand wavelength sweeps per second over a sweep range >100nm at 0.1nm linewidth in the region of 1050 to 1600 nm.
