500mw laser pointer for presentations and presentations
Commercial Laser Pointers 500mW laser pointers are generally designed to assist presenters with presentations or presentations. A high-tech alternative to retractable metal pointers, the high power laser pointer beam will create a small spot of light on the object it is aimed at. It draws the audience's attention to specific key points in the slideshow. Pointers are also used for other purposes, such as aiming other lasers, pipe penetration in construction, and as a gun proxy. More: Green laser pointers can travel tens or even hundreds of miles in the dark. With their powerful energies, high-intensity beams, and extended reach, they create a pheromone only seen in sci-fi movies.

200mw green laser pointer
These types of events have started to spur government action. In November 1997, the UK banned the sale of certain types of higher performance pointers. In December 1997, the U.S. Food and Drug Administration issued a warning against their use by teens (see below). The FDA is issuing a warning to manufacturers about UV lasers telling users not to stare at the beam. These warnings are small and easy to ignore, but as shown, widely violated the device. A green laser pointer with the same power is 6 times brighter than a red laser pointer!
If the laser diode bar or array is already mounted in a large heatsink, 10 or 20 seconds is fine. But if it's just a small gathering, cooling is essential even for that short time. Where the diode bank itself has water cooling lines, it may require tap water even if the power is on for a while. If in doubt, assume that cooling is important no matter how short the test is.

While it is usually evident when a low-power laser diode changes from an LED to a laser, a high-power diode emits a lot of power through the LED near the green laser pointer threshold. For example, a typical 1 W laser diode can produce 10 mW or more of incoherent light near the lasing threshold. The easiest way to find the laser threshold is to use a spectrum analyzer, which will show if narrow laser lines buy green very powerful laser appearances on a broad fluorescence spectrum. Without such an instrument, the laser threshold current can really only be estimated.
