Why can my dog see a red laser pointer?
This isn't the first time Chinese power companies have found a better way to clean power lines. Workers in another province debuted their flamethrower cleaning services a few months ago. But this new 5000mw high power laser pointer is arguably easier and safer to use. It's about a kilowatt CO2 laser and needs its own power supply and cooler, but it can stay on the ground while workers clear the lines.
A laser pointer that pilots can use
Green laser pointers pose a risk to people and buildings if hit by the beam, an obvious possibility in crowded cities. What's more, green laser pointer pose a risk to aircraft flying overhead. For the laser to operate smoothly and maintenance-free during three months of spaceflight, it had to withstand shock and vibration, as well as extreme temperature fluctuations between minus 30 and plus 50 degrees Celsius. "We have developed optomechanical components for the laser, such as mirrors and lens mounts, that meet these requirements and maintain very precise settings.

Material
The laser is funded by Strathclyde and the Scottish Universities Physics Union (SUPA), which works with Strathclyde to share resources, strategic planning and expertise in physics research. It was designed and built by Thales, a global technology leader in the aerospace, transportation, defense and security markets.
Blue laser ratio has great uses
Use the supplied battery to measure the current and voltage drop across the laser pointer, then simply calculate the series resistance of the plug-in power supply to be connected. To be on the safe side, measure again with the plug-in power connected, changing the resistance if necessary. Laser pointers are not toys and should not be used as toys. A situation where an animal turns or jumps in and hits you in the eye can happen very quickly. There might even be someone nearby. Take a flashlight and you have a similar effect. The most commonly used 30000mw lasers use green wavelengths. "But if the attacker uses a different type of laser, the goggles will be useless." Also, many pilots are reluctant to wear them. What got you that idea? In any case, the laser pointer contains a power source.
Installed a new battery on the 5000mw laser pointer and played a bit ;-) I also took a photo of the monitor...sounds ridiculous but you never know...they think it's edible. All the energy of a light particle (photon) can be absorbed by one of the electrons, or split when a photon hits two electrons of a helium atom. Electrons leave atoms regardless of energy transfer. This process is called light emission or the photoelectric effect and was explained by Albert Einstein at the beginning of the last century. I'm not going to be so foolish, these laser pointers are very dangerous and can hurt eyes, even fish.
