abstract = {In Fourier domain mode locked (FDML) lasers, extremely precise and stable matching of the filter tuning period and light circulation time in the cavity is essential for ultra-low noise operation. During the operation of FDML lasers, the ultra-low noise mode can be lost due to temperature drifts of the already temperature stabilized cavity resulting in increased intensity noise. Until now, the filter frequency is continuously regulated to match the changing light circulation time. However, this causes the filter frequency to constantly change by a few mHz and leads to synchronization issues in cases where a fixed filter frequency is desired. We present an actively cavity length controlled FDML laser and a robust and high precision feedback loop algorithm for maintaining ultra-low noise operation. Instead of adapting the filter frequency, the cavity length is adjusted by a motorized free space beam path to match the fixed filter frequency. The closed-loop system achieves a stability of ~0.18 mHz at a sweep repetition rate of ~418 kHz which corresponds to a ratio of 4×10<sup>-10</sup>. We investigate the coherence properties during the active cavity length adjustments and observe no noise increase compared to fixed cavity length. The cavity length control is fully functional and for the first time, offers the possibility to operate an FDML laser in sweet spot mode at a fixed frequency or phase locked to an external clock. This opens new possibilities for system integration of FDML lasers.},

abstarct = {The absorption of laser pulses by tissue leads not only to the generation of acoustic waves, but also to nanometer
to sub-micrometer scale displacement. After the initial expansion, a quasi-steady state is achieved in a few
microseconds. Previously we introduced the concept of thermo-elastic optical coherence tomography (TE-OCT)
to \visualise" the rapid thermo-elastic expansion by measuring the Doppler phase shift rather than \listening"
to the acoustic wave as in photoacoustic imaging. In this study, we built a microscopic setup for high-speed
3D TE-OCT imaging, by means of thermo-elastic optical coherence microscopy (TE-OCM). The repetition rate
of pulsed laser was set to 100 Hz and the line rate of the OCT system is 1.5 MHz. The OCT beam and the
laser pulse were focused upon the same location on the sample FWHM spot sizes of 300 m for the pulsed laser
and 40 m FWHM for the OCT beam. For each laser pulse, an M-mode OCT image consisting of 90 A-lines
was acquired. The Doppler phase shift was extracted by comparing the phase signal before and after the pulse
arrival. Within 6 minutes, a 3D TE-OCM image (10 x 10 x 4 mm3) can be acquired and processed. Imaging
experiments were carried out in swine meat using 1210 nm excitation wavelength to highlight lipid in tissue.
The results show that no signicant displacement was detected in swine muscle while strong displacement was
observed in lipid, owing to the optical absorption features. Furthermore, fatty tissue is easily identied in the
3D TE-OCM image while the conventional OCT images provides the structural information.},

abstract = {MHz-OCT systems based on FDML swept laser sources combined with the massive parallel processing capabilities of modern computer hardware enable volumetric imaging, processing and stereoscopic display at video rates. The increasing image quality and speed might enable new fields of application where the volumetric OCT completely replaces stereoscopic microscopes instead of being a mere supplement. Aside from the depth resolving capability, a particular advantage is the ability to display a whole image volume from arbitrary points of view without the need to move the actual microscope or to rotate the patient’s eye. Purely digital microscopy is already offered as alternative to traditional through-an-eyepiece surgical microscope. We explore the use of virtual reality to present digital OCT microscopy images to a trained surgeon, carrying out a series of surgical procedures ex-vivo on a porcine eye model.},

abstract = {Optical coherence tomography (OCT) applications like ultra-widefield and full eye-length imaging are of high interest for various diagnostic purposes. In swept-source OCT these techniques require a swept light source, which is coherent over the whole imaging depth. We present a zero roll-off 1060 nm Fourier Domain Mode Locked-Laser (FDML-Laser) for retinal OCT imaging at 1.7 MHz A-scan rate and first long-range imaging results with it. Several steps such as improved dispersion compensation and frequency regulation were performed and will be discussed. Besides virtually no loss in OCT signal over the maximum depth range of 4.6 mm and very good dynamic range was observed. Roll-off measurements show no decrease of the point-spread function (PSF), while maintaining a high dynamic range.},
