which didn't seem bad using the scope last weekend, it should be a big improvement. The 3 focused lasers in the eyepiece are not dead center, but they are closer now than they were. I did not check for eyepiece tilt, because I am just getting my feet wet with this, ...

In this QED scheme, on the one hand, because of the quantum radiation losses, the transverse phase space of electrons is confined36,31, and the electrons are easily trapped in the center of laser-produced plasma channel; on the other hand, due to the additional contribution of radiation ...
The cost of the laser mod was said to be about USD $50. It appears the beam is fully enclosed within the case, so it could not enter a person's eye. However, if the case was jarred in such a way as to knock one or more mirrors out of alignment, then laser light could exit th...
Two frames from the South Australia Police helicopter. In the first frame the laser beam is aimed to the left of the camera. In the second frame the beam is aimed directly at the camera lens. The human eye would have a similar effect, first seeing the beam then being dazzled and flash...
In recent decades erbium doped materials have become a research hotspot due to 2.7 μ m mid-infrared emission, which has wide applications in both civilian and military fields such as remote sensing, atmos- phere pollution monitoring, eye-safe laser radar, medical surgery and precision ...
The LaserTech ULS is a class-1, eye-safe laser that operates at 905 nm (Near-Infrared) with a configurable pulse-repetition frequency (PRF), set to 4000 Hz with 10-point averaging to yield an effective PRF of 400 Hz during the Negribreen campaigns. Beam divergence is 3 mrad, which res...
The measuring laser beam then passes through the “cat’s eye” system, consisting of the lens (11) and a small reflecting mirror fixed on the membrane (10), and again enters the photodetector (15). An interference pattern forms on the photodetector, the signal from which comes to the ...
