A useful device - the series of green laser pointer

Many people still do not know the laser pointer is despite its rich applications in the field of entertainment and science.I don't say that without a reason.I met a friend yesterday, tell him I want to buy a green laser on the business presentation.He does not know how to do a laser can be said and I explained everything to him.Later on, I realized that not everyone know about laser equipment, perhaps only professionals or laser followers are familiar with it.
A laser pointer is a very small device, can emit visible power narrow beam, it is used to highlight the object through the illuminate them with a small bright spot.The laser can be divided into many categories, including green laser, red laser, blue laser pointer etc..Now a green laser pen has become a leader in all its shining laser beam, clearly visible, cheap price and high quality.Green laser with output power of different, for example, some of them range from 1 kW to 1000 kW, people to choose the right according to their purpose.
In general, less than 5 mW laser is safe to use.However, people sometimes had to buy power to accomplish their mission.This is because many experimental results without enough power.The problem is how to meet the various needs of a large number of different intentions?
With a wavelength of 532 nm, Helios series of green laser pointer output power from 5 kW to 150 kW, it can meet almost all the requirements from different users.The series of green laser is less than 50 MW is very suitable for indoor demo.Teachers' seminars, business people and interior decoration are using the green laser to help them complete the task.This is indeed a capable assistant coach pointing and demonstration.
The laser ranging from 50 kW to 100 kW is mainly used to indulge in fantasy and the observation of celestial bodies.It is difficult to explain and arms waving not need to use the laser pointer.Green laser is so strong, so that you can see its light even in the day, not to mention in the dark.Above 100 mW laser is very useful for those who want to professional research and combustion experiments.In addition, the high power laser equipment can be used in hiking and outdoor activities.The laser beam is bright enough to scare off large wild animal and the user can send a distress signal in case of emergencies.
High power laser pointer injury is serious, it is important for people to take precautions when operating the laser pointer.
