Data from a recent integrated ground test of the Alpha high-energy laser, its beam director telescope and the associated beam alignment and correction system have provided the team developing the ...

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts, and decided to show us how it operates, tells us what we should keep in mind when designing such a driver, and talks about ...

Cailabs plans to boost production of optical ground stations to 50 per year by 2027. Credit: Cailabs Laser company Cailabs has raised €57 million ( ($67 million) in additional financing and plans to ...

Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

Design, development and validation of a speckle-based, visible spectrum, image sensor modulation transfer function (MTF) test system. Investigated the technique of using visible (532nm) laser speckle ...

For the last five years, Air Force Special Operations Command has been working toward incorporating a high-energy laser weapon on its newest AC-130J gunship. It now plans to test-fire a 60-kilowatt ...

Engineers know that measuring dc or low-frequency electrical power is fairly straightforward, but such measurements become more difficult as you go up the spectrum into the tens-of-gigahertz range.

Non-contact laser welding offers several advantages when it comes to joining one plastic part to another. It works on the principle of partial transmission which lets a laser’s light travel through ...
