Low-coherence optical fibre speckle interferometry... Sources including light-emitting and superluminescent diodes and multimode laser diodes are compared, and the use of a multimode laser diode source in pulsed mode is shown to improve depth resolution....
Recent advances in microstructured fibers for laser delivery andWe report recent advances in the development of fibers for the delivery and generation of both single-mode and heavily multimode laser beams as well as recent progress in fibers for supercontinuum generation in spectral regimes spanning the visible to mid-IR....
Spatial combining of laser-diode beams for pumping an nproA free-space optical beam combiner now undergoing development makes it possible to use the outputs of multiple multimode laser diodes to pump a neodymium-doped yttrium aluminum garnet (Nd:YAG) non-planar ring oscillator (NPRO) laser while ensuring that the laser operates at only a single...
Fiber dispersion induced nonlinearity in fiber-optic links with multimode laser diodesIn analog RF fiber-optic (FO) links with directly modulated multimode laser diodes (LD's), nonlinear distortions of the received modulation signal occur due to fiber dispersion....
