It also planned to showcase Pico Tunable Laser which is silicon photonics based ultra-narrow linewidth
. Some of the key players in the photonic crystals market are Furukawa Electric Co.
The company announced limited availability of the 'Nano' version of its ultra-narrow linewidth
integrated tuneable laser assembly (ITLA) at the event.
Yizhi Liang, assistant professor at the Institute of Photonics Technology, explained that fibre lasers such as this --which have a kilohertz-order linewidth
--can be exploited as sensors due to their ability to offer a high signal-to-noise ratio.
The Single Frequency DPSS laser--Solo 640--exhibits excellent performance characteristics (beam quality, wavelength and power stability) and is particularly suited for holography, which depends on the power, stability and linewidth
of a laser to give clear images with a deep field of view.
At the CS, the lightwave is generated from an external-cavity laser (ECL) at 193.26 THz with a 100 MHz linewidth
, which is divided into two parts by an optical power splitter.
In order to achieve different memories, we choose a narrow linewidth
laser delivering 100 ns, 15 ns, and 0.7 ns pulses of a 100 [mu]J energy as the pump while the Stokes pulse power is equal to 10 W.
The surface resistance is proportional to the resistivity of the material and is inversely proportional to the thickness and linewidth
. The frequency-selective surface is printed with a thin ink layer to produce a uniform sheet of security paper; we designed a Jerusalem structure with a thick line width.

The difference is that the coherent [PHI]-OTDR requires a light source with a longer coherence length and narrower linewidth
. The light from a coherent light source is modulated using an external modulator, and it is converted to continuous short optical pulse trains.

These synthesized PEG-Gds were also evaluated by the linewidth
at half height of each PEG contrast agent through NMR measurements to investigate the cause of the contrast agent enhancement.
