Science/Technology / Red Laser Will Be Transmitted Across Htpow by michalescot: 3:35am On Jun 28, 2017
The U.S. Navy mounted a 30-kilowatt laser gun on the deck of the USS Ponce and blasted some small targets. Portable device that provides automated measurements of the propagation characteristics of CW and pulsed lasers in under one minute.

And researchers are even investigating whether Red Laser could be used defensively in space. They'd pretend to move out of the laser just in time. Orange cables run from the back of the laser into the interior of the helicopter.

The eye-safe Red Laser will be transmitted across the river to evaluate the performance of a laser system at long range over water. His announcement made headlines, but someone said that was not the laser to be tested Tuesday. The focused light of lasers can be used for microscopy.

Now that you're informed, tan and get laser during the Summer at your own risk! They are invited to have a look at the newest consumer and industrial diode, commercial laser products. The real key to making our system work is the interference between two laser beams on the sensor.

Detectors work by illuminating a material with a laser tuned to a wavelength . Vibrates precisely at the frequency of the combined laser beams. It can cause photo sensitivity should absolutely avoid laser in the Summer months.

Science/Technology / The Spot Size Of A Burning Laser Is Indicative Of A Couple Of Factors by michalescot: 10:53am On Oct 22, 2016
The measurement sensitivity of the pointing direction of a burning laser pointer blue beam is ultimately limited by the quantum nature of light. To reduce this limit, we have experimentally produced a quantum laser pointer, a beam of light whose direction is measured with a precision greater than that possible for a usual laser beam. The laser pointer is generated by combining three different beams in three orthogonal transverse modes, two of them in a squeezed-vacuum state and one in an intense coherent field.

The United States Food and Drug Administration (FDA) encourage people to avoid buying lasers or items with lasers if the green laser pointer power is more than five mW. Presentation device includes laser pointer with remote control and scroll up/down buttons. Lasers with an output of more than five mW can cause irreversible damage to your child's eye. Transmission distance up to 50 feet. Receiver has 30" extension cord. Plug and play technology. Deluxe gift box contains base for USB port and laser pointer.

This self-leveling point laser pointer is accurate to 1/4" per 100'. Its single lever power switch locks pendulum in the off position for added durability. A built-in magnetic pivoting bracket mounts easily on metal surfaces.Get the point across at the speed of light with this high-output, Class II laser pointer that fits in the palm of your hand.For $50 a presentation mouse can do about 90% of what a $1200 whiteboard can do and it has a laser pointer.Cool.Mr. Omidyar decided to sell a broken laser pointer.

The difficulty with this evaluation is that it is for the most part subjective, however the picture of the laser spots on a wall speak for themselves. The Jasper is the larger spot."The spot size of a laser is indicative of a couple of factors, one is the beam diameter as it exits the cavity, the other is the divergence of the beam.



To enable an electronic toy to be activated by a laser, the engineers at CanAssist designed a box containing four sensors that detect light. This box is attached to a store-bought toy and, when the 2000mw Laser beam successfully hits the box, a switch is triggered to turn on the toy. This is a laser that the laser safety officer on my campus (a good friend in the office across the hall from me), made me register and agree not to ever use as a laser pointer indoors infront of students ever ever ever.

The 10mW Green Cross Alignment Laser emits a very visible green line that can be adjusted to align horizontally and vertically. Meant for indoor use, it comes with wall adapter that can be plugged into Canadian household power outlets. Please be responsible, Canada banned high-powered handheld laser pointers, plug-ins are okay.

Science/Technology / How Lasers Are Generated by michalescot: 7:32am On Sep 27, 2016
Technologically, as in so many other areas, commercial industry is leading the way: "There are thousands of these 300mw Green Laser Pointer systems out in industry applications all over the world." Meyer told me. "I can buy lasers for welding, for cutting",When Gunzinger and his CSBA colleagues started exploring laser weaponry three years ago, he said, they expected that technological problems would be the major limiting factor: "We came out of that study saying, mmm, it really might be more [about] resources." An important fact to note is that the burning laser pointer generator has to be "pumped" by filling it with a higher energy/shorter wavelength compared to the laser beam that will emerge.



For instance, a 20 kW version of DE-STARLITE operating for 15 years could deflect an Apophis-size (1,066 feet) asteroid at a distance equal to Earth's diameter.Zhang and his colleagues claim that if DE-STAR had a 330-feet-wide phased laser array, it could divert volatile-laden asteroids 330 feet in diameter by initiating engagement at about two million miles. A 300mw green laser pointer version could deflect all known threats up to 1,640 feet in diameter with five-year laser activity.However, DE-STARLITE, being a much smaller and less expensive system, is the more practical option.

You cannot pump it with the same wavelength as the result beam, or the act of pumping the burning laser pointer will simultaneously stimulate emission, and you'll never get anywhere. And given the current pressure on the defense budget, resources are just going to get tighter. "Under this contract, Northrop Grumman will complete a conceptual design for a complete laser weapon system to be integrated onto a destroyer or other suitable surface ship.” In 2012, the company introduced Gamma, a military laser that made generational advances in packaging solid-state laser technology into much smaller, lighter, more reliable and more affordable units for operational use. 

Northrop Grumman has decades of experience in developing, integrating and field-testing 300mw green laser pointer weapon systems.Through its work on behalf of the German government and an application of its own resources, Rheinmetall has acquired expertise in this field in recent years. For details about how lasers are generated, read the details in the link above.The latest live fire demonstration, a joint effort by Rheinmetall’s Weapons and Munitions and Air Defense divisions, shows that the group possesses the skills to develop complex burning laser pointer weapon systems.
