In an era demanding ever-smaller, more efficient, and higher-performing light sources, particularly in the short-wave ...

Abstract: We compare narrow and wide laser beams in a free-space optical (FSO ... We propose to employ a divergence angle of a wide beam in the range [0.07°, 2.002°] to relax the steering speed of the ...

Abstract: In this paper, a microstructured laser with modulated periodic microstructures for beam control is proposed for the first time. Lasers using modulated periodic microstructures can emit beam ...

Dynamically controlling the beam-divergence angle of the transmitted signals has the potential ... This is the case in most realistic space laser communication systems, since the optimum beam ...

In order to reduce the divergence angle after the light pipe input ... and Laurenzis, M. (2014) Beam Shaping of Laser Diode Stacks for Compact and Efficient Illumination Devices at the French-German ...

Because even a minor misalignment between the transceivers of the FSO system can result in failure of the FSO link, controlling the line of sight directivity for FSO beam propagating at a narrow-angle ...

Instead, the NFI uses an array of laser-light amplifiers the size of three football fields to focus laser beams on hydrogen fuel pellets in a 33-foot-wide (10 meters) spherical metal "target chamber." ...

Since the speed of light is constant, distance can be readily calculated by measuring the time it takes for the beam ... laser. The safety rating of a LiDAR depends on the power, divergence angle ...
