The selector-free single-frequency operation of an Yb-doped fiber laser with scanning in the
range of∼ 20 nm is demonstrated. The frequency and intensity evolution is shown to be …

Dynamic population inversion gratings induced in an active medium by counter-propagating
optical fields may have a reverse effect on writing laser radiation via feedback they provide …

We report on spectral characterization technique of self-organized dynamical distributed
feedback (DDFB) in a self-sweeping Yb-doped fiber laser. The DDFB is originated from gain …

Gain-guided diode lasers usually have emission wavelengths determined by the
manufacturing process, with typically 0.5–1-nm bandwidth. Furthermore, their beam quality …

In this letter, we show that polarization coupling and asymmetric diode-laser feedback can
be used to combine two diode-laser beams with low spatial coherence into a single beam …

I personlige dagbogsblade fra 1998 og 1999 med udgangspunktet i samlivet med datteren
Laura på 3 år reflekterer forfatteren over sin samtid, dens mennesker og begivenheder-fra …

We narrowed the spectral bandwidth of our 2 W broad-area laser to 8±1 GHz with a coarse
tunability of 12 nm centered near 790 nm in an external cavity. Our passively stabilized …

We present a highly bright output radiated from a single-stripe high power laser diode,
known as a broad-stripe laser diode (BS-LD) with ring-type self-pumped phase conjugate …

The maintenance of high-spatial-quality radiation in laser devices as they are scaled to high
powers is important for many practical applications, including laser material processing …
