A 30mW Green Laser Pointer pen (Light Amplification by the Stimulated Emission of Radiation) is a beam of coherent light that is man made and not found in nature. You can demonstrate the inherent power of a laser by enabling an inexpensive laser pointer 200mw to project the laser light it creates at its full intensity. The procedure involves deactivating the circuit board that limits the output of the laser light and can be done by anyone who feels comfortable using a soldering iron. The “burning” laser pointer will not be the stuff of mad scientists, but it will demonstrate how powerfu lBlue Laser Pointer 10000mw light can be at very close distances.
Wavelength also comes into play as lower spectrum wavelengths tend to have more energy.
Basically a 405nm will burn better than a 445/450/532/650 in the visible range.
You will never burn anything at the moon, that's just silly. All 1000mw laser pointer red diodes have a value listed as mRad, which tells how much the beam will expand over time. Optics can help this, but for practical purposes it will always exist.
Also, generally to pop balloons, you need at least a 30-50mw laser. To burn, no less than 200mw.
The most important thing when using lasers like this is to wear color blocking safety glasses for the laser you are using. Anything over 5mw can cause damage, and burning lasers can permanently blind you. They should be treated no different than a firearm.
A split-second look into the beam of any Laser Pointer for sale , at any classification, can result in flashblindness. Flashblindness is temporary and vision returns to normal with no long-term effects. However, a longer look into the beam can cause more serious damage to the eyes. This damage may be worse if theYellow 50mw Laser Pointer beam is projected through a piece of optical equipment, like a telescope or binoculars. It is very important to read the label and be cautious when using hand-held lasers and laser pointers.
Till a few years ago,50mw Green Laser Pointer Pen light technology was the exclusive domain of the technological shrinks. Today, the word laser concocts images of powerful beams of light, destroying everything that they touch. The ‘Star War’ scenario, where different planets go to war throwing laser pointer 3000mw beams at each other, is not far from the mind as well. With the advancement in technology, laser has been brought down from its high tech pedestal.
Laser stands for Light Amplification by the Stimulated Emission of Radiation. One basic type of laser consists of a sealed tube, containing a pair of mirrors, and a 10000mW 532nm green laser pointer that is excited by some form of energy to produce visible light, or invisible ultraviolet or infrared radiation.
There are many types of laser pointer, Green Laser Pointer 3000mw(from 5mw to 1000mw),blue laser pointer (from 1000mW to 5000mW), violet blue laser pointer/purple laser pointer(from 5mw to 500mw), red laser pointer(from5mw to 200mw) and laser light etc.
20000mw laser pointer and focusable laser pointer 100mw can light matches and even cigarettes easily, the red laser pointer and purple laser pointer in flashlight shaped are water-proofed and with focusable lens wihch can light matches with in 3meters in 2seconds.
Laser Pointer Blue 30000mw seems that the charming blue laser beam nearly lighting up the whole space. Its blue laser beam seems much more attractive and marvelous than any other type of laser devices andled lights have projected.

An astronomyLaser Pointer Blue 30000mw looks much like its regular red cousin on the outside. It is shaped like a thick pen. The beam of an astronomy 20000mw laser pointer, however, is green and about 60 times brighter than the red version. The curious properties that makes these pointers extraordinary is that the beam creates the illusion to the human eye that it is stopping at the object toward which it is pointed. The beam can be followed from hand to sky to accurately point out objects as small as stars.
The standard for an astronomy laser pointer is 5 milliwatts (mW) of power and a laser wavelength of 532 nanometers (nm). Higher wattage pointers, up to 500 mW are available, but are not always safe to use. The technology used to emit a laser of this power and frequency is more complicated than the common red type. Because a direct diode would cost thousands of dollars, it is necessary to mechanically and electronically convert a laser beam of a frequency that can be cheaply produced. The extra technology makes the astronomyGreen Laser Pointer 3000mw
more expensive than the red pointer.
10000mW 532nm green laser pointer can often be found in office supply stores and electronics retailers. They can also be found by shopping on Internet. There, they will find the Laser Pointers category.In addition, the laser colors available on Internet include red, green, blue, purple, and yellow. Buyers who are in the market for ultra-powerful lasers can also find a variety of suitable safety glasses in the laser pointers category. As a result, Internet provides buyers with everything that they will need to safely use a wide range of laser pointers.

Yellow 50mw Laser Pointer can make the work a lot easier. When pointing out construction details, using a laser pointer 300mw is a convenient way to get the message across without any extra effort.
The range of a laser pointer may also be understood as the maximum distance from which the spot on the screen can be seen. That kind of range is normally not limited by the beam divergence but by the overall optical power (apart from the wavelength and level of ambient light), since the issue is not the comparatively minor divergence on the way from the 5in1 30mW Green Laser Pointer to the screen, but rather the huge divergence of the scattered light on the way back. Therefore, someone standing next to the illuminated screen would easily see the spot when it is already hardly perceivable from the position of the laser pointer.
Unlike the beams of red or blue lasers, the beam of a Green Star Laser Pointer 10mW is actually visible.Hight power green laser pointers well suited for stargazing because spectators can see the beam going all the way from the laser pointer up to the star at which it is pointing. Users can take their laser pointers in hand, or even attach them to telescopes, in order to align the telescopes with certain stars.
