The pumped crystals in a green laser pointer have an optical coating that causes the crystals to give out mostly 1064nm infrared light that is frequency doubled by another crystal to green 532nm light. The pumped crystals in a blue laser pointer have a different coating that causes the crystals to give out mostly 946nm infrared light that is also frequency doubled by another crystal to 473nm light.

150mw green titanium laser pointer beam
Laser pointers use the laser technology where a light is amplified using battery power. At present, laser pointer batteries are rechargeable like CR123 or 18650 battery. The lights of pointers’ laser available today are 473nm, 405nm, 650nm, 980nm,1064nm,808nm and the most common 532nm green beam. Now, green laser pointer is the widely used color of laser because of its high visibility where you can clearly see the light of the beam being produced. Compared to the yellow light which may diffuse, green light can be more stable when it comes to temperature and background light. Green laser pointer has a high frequency having the wavelength of up to 532nm that is powerful enough to become very visible. Other high frequency laser beams available in the market today are violet and blue. You can still find red or red-orange beams that is more powerful that its ancestors.
When choosing a laser pointer, you can look at different strengths and according to the need. These laser pointers beams can be hazardous to the eye but the good news is that most of the product designs of laser pointer today are created with safety features. If you want something that you can use as light or just a toy then you can choose the 532nm 150mw titanium green laser pointer. But if you want something that you can use in parties, you can have the powerful lasers such as green, red, blue, and violet. But be responsible in using it because pointing it to the eye of person may cause blindness or eye defect. Moreover, the eye injury caused by laser irradiation is cumulative, so even the little injury is not obvious enough, but don't wait until it's too late. You must wear the laser safety goggles when operate these lasers and encounter these lasers beams.

Surprising Laser Safety Goggles for Laser Pointers
Laser Safety Goggles applies the optical absorption principle: its target light source is not selective, and one can nearly block any diffused light radiated from the laser; the incident angle of the light source is not selective either and they receive the equally efficient protection. With faster light reaction and higher damping decrement, these goggles are also anti-wear, and even there is any scratch, the laser safety is not affected.
The laser safety goggle is highly effective, explosion-proof, and eyes protective. Laser safety goggle is light weighted, high in toughness and unbreakable, and has been widely recognized and recommended by international security organizations and laser users. Completely meeting the safety requirements of GJB1762-93 "laser protective glasses physical health standards," and it's very comfortable, beautiful and reliable.

Non Lethal Deterrent--Green Laser Dazzler
In terms of their use, a common dilemma often faced by soldiers deployed in Iraq and Afghanistan is how to warn/deter suspicious or aggressively driven vehicles that are approaching their checkpoint or convoy operations with out using potentially lethal force. This is particularly a problem during night operations when identification is more difficult. Laser dazzlers have been especially useful in this regard as a means of non lethal deterrent.

Skin Conditions Treated by Lasers
Unwanted hair can be effectively removed or reduced using lasers such as 635nm lasers or 1064nm lasers. These lasers target the melanin within the hair shaft and bulb causing the destruction of cells. This results in the slowing down the ability of hair growth.
Laser resurfacing allows the collagen in the skin to be rebuilt, making a patient look younger by reducing the wrinkles in the skin. The most commonly used noninvasive device, green lasers or red lasers emitting diodes have been used to stimulate the fibroblasts in the skin to produce collagen, elastin and glycosaminoglycans to rejuvenate the skin.
It is important that the anybody using laser devices should be thoroughly trained and the patients and the clinic staff be given eye protection. You must be wearing laser safety goggles or protective goggles. Patients should keep in mind that laser treatments are basically burns, which can cause temporary pain, infection and redness. Understanding the inherent risks and complications is crucial. So, before going for a laser treatment, please consult a qualified laser surgeon.

Marvelous Titanium Products
Since titanium does not become magnetized, it is used in the structural parts surrounding computer components such as disk drives and microchips, which can be ruined by stray magnetism. Other common applications of titanium include shape memory eyeglass frames, watches and jewelry.
