Green Laser Pointer 10mW Information
Laser pointers (sometimes known as laser pens) are compact, handheld laser devices. They are typically used to highlight an object or point of interest by illuminating it with a bright spot of colored light.
Laser Pointer Basics
As shown in the200mw green laser Selection Guide, all lasers consist of three components: an energy source (also known as a pump), a laser (or gain) medium, and an optical resonator; these components are shown in the image below. Essentially, the pump provides energy which is amplified by the gain medium. This energy is converted into light and is reflected through the optical resonator which then emits the final output beam.
While early 100mw laser pointer were pumped by helium-neon (HeNe) gas, nearly all modern laser pointers use electrically-powered laser diodes as their energy source. The image below shows a deconstructed laser pointer and identifies its main components. In the image, the 1064 nm laser diode — which is controlled by a separate circuit and current from a battery pack — represents the pump, the KTP/YAG crystal represents the pointer's gain medium, and the focusing barrel is the optical resonator.
Curious dogs in the night-time: Hilarious video shows pooches chasing green 100mw laser pointer up and down street as more join in.At first it begins with two dogs chasing after a laser projected on the street from a high rise building.
But just seconds later every dog in the neighbourhood joins in with the game as they try in vain to catch the illuminated dot by running up and down the street in Kolomna, near Moscow.
Among the tens of thousands of viewers on YouTube was Steph Bond, who said: ‘Any animal caught chasing a laser gets an automatic +1 added to its cuteness rating. That's international law.Animal behaviourists say the rapid and random movement of laser pens triggers the predatory instincts of animals, which makes them obsess about an ultimately unsuccessful chase.
