“…This can be achieved with an additional optical amplifier either as a booster at the output or as an extra gain element in the laser resonator. Different configurations have been demonstrated employing another standard SOA [154,159], a tapered semiconductor amplifier [160], or a rare-earth-doped fiber amplifier [148,161].…”

Diode lasers are by far the most efficient lasers currently available. With the ever-continuing improvement in diode laser technology, this type of laser has become increasingly attractive for a wide range of biomedical applications. Compared to the characteristics of competing laser systems, diode lasers simultaneously offer tunability, high-power emission and compact size at fairly low cost. Therefore, diode lasers are increasingly preferred in important applications, such as photocoagulation, optical coherence tomography, diffuse optical imaging, fluorescence lifetime imaging, and terahertz imaging. This review provides an overview of the latest development of diode laser technology and systems and their use within selected biomedical applications. 670 nm external cavity diode laser for Raman spectroscopy built on a 13 × 4 mm 2 microbench (Copyright FBH/Schurian.com).

“…Similar components have also become available for the intermediate band between 1 µm and 1.1 µm, although in general with lower performance. Intense research is thus aiming at the development of high-speed tunable lasers with adequate bandwidth and output power for these wavelengths [37,38]. Considering this, none of the different OCT implementations can be pointed out as being superior.…”

Optical coherence tomography (OCT) is a non-invasive imaging technique providing real-time twoand three-dimensional images of scattering samples with micrometer resolution. Mapping the local reflectivity, OCT visualizes the morphology of the sample. In addition, functional properties such as birefringence, motion or the distribution of certain substances can be detected with high spatial resolution. The main field of application is bio-medical imaging and diagnostics. In ophthalmology, OCT is accepted as a clinical standard for diagnosing and monitoring treatment of a number of retinal diseases, and OCT is becoming an important instrument for clinical cardiology. New applications are emerging in various medical fields, e. g. early-stage cancer detection, surgical guidance, and early diagnosis of musculoskeletal diseases. OCT has also proven its value as a tool for developmental biology. The number of companies involved in manufacturing OCT systems has increased substantially during the last years-especially due to its success in opthalmology-and this technology can be expected to continue to spread into various fields of application.

“…In the 1060 nm wavelength regime, FDML operation has already been demonstrated at up to 249 kHz [15,[17][18][19]. However, the large dispersion, high loss and pronounced polarization effects at 1060 nm in the km long delay fibre of FDML lasers complicate FDML operation at 1060 nm compared to 1310 nm.…”

The wavelength swept amplified spontaneous emission (ASE) source presented in this paper is an alternative approach to realize a light source for high speed swept source optical coherence tomography (OCT). ASE alternately passes a cascade of different optical gain elements and tunable optical bandpass filters. In this work we show for the first time a wavelength swept ASE source in the 1060 nm wavelength range, enabling high speed retinal OCT imaging. We demonstrate ultra-rapid retinal OCT at a line rate of 170 kHz, a record sweep rate at 1060 nm of 340 kHz with 70 nm full sweep width, enabling an axial resolution of 11 μm. Two different implementations of the source are characterized and compared to each other. The last gain element is either a semiconductor optical amplifier or an Ytterbium-doped fibre amplifier enabling high average output power of >40 mW. Various biophotonic imaging examples provide a wide range of quality benchmarks achievable with such sources.
