The influence of the front facet reflectivity on the spectral linewidth of high power DFB (distributed feedback) diode lasers emitting at 780 nm has been investigated theoretically and experimentally. Characterization of lasers at various front facet

Highly strained InxGa1−xAs QWs are commonly used for laser diodes in the wavelength range beyond 1100 nm, but they suffer from strain induced formation of defects. The effect of different laser structures and different laser layouts on the aging be

In this letter, the mode hop characteristics of distributed Bragg-reflector ridge waveguide lasers emitting at 1120 nm with different resonator geometries and facet reflectivities are investigated. The emission wavelength is measured systematically f

Optical feedback originating from the interfaces of the periodically poled domains of a nonlinear crystal is usually blocked by a bulky optical isolator to avoid an influence on the pump source. Here, a nonlinear bulk crystal with a slanted design of

In this study, the authors present experimental results on 6 mm long monolithic passively colliding-pulse mode-locked (CPM) lasers. The AlGaAs-based devices with In x Ga1−x As y P1−y double-quantum-well (DQW) active regions emit between 860 and 8

Pulsed diode laser sources in the yellow-green spectral range are highly demanded for applications like label-free imaging or stimulated emission depletion (STED) microscopy. However, direct emitting diode lasers are not yet providing sufficient emis

Distributed Bragg reflector tapered diode lasers (DBR-TPL) emitting at 1064 nm are highly efficient and narrowband light sources which e.g. can be used for the treatment of eye diseases including the two main causes of blindness worldwide (i.e diabet

Laser structures for different operating temperatures were developed. Higher temperatures need an increase in barrier height to reduce carrier leakage. Best results for an emission wavelength of ≈800 nm were obtained using an asymmetric structure c

We demonstrate a continuous wave 133 mW laser module at 560.5 nm on a 50 mm·10 mm optical bench. The setup consists of a 1121 nm distributed Bragg reflector ridge waveguide laser and a MgO:LiNbO3 quasi-phase matched ridge waveguide crystal, which ar
