If you have a clear observation, you will find that portable laser pointers are available from Perfectlasers.net, and portable red laser, green laser, blue laser, yellow laser are all can be found here.

I would have to admit that it is the first time I saw such a large variety of portable laser pointers. Different from the usually seen laser pointers, the portable lasers are mainly featured by its high output power and flashlight design. Take portable blue laser for example, the highest output power can reach 40mw or even higher. I cannot imagine the difficulty to create a 40mw portable blue laser.

A blue laser pointer is usually produced with an output power rang from 1mw to 30mw, while the portable blue laser has breakthrough it and make higher power laser available. As you know, the blue laser pointer has a unique use in astronomy, military, medical, or any other researches, the 40mw portable blue laser is really in badly need.

Since portable laser pointers are more powerful than laser pointers, you should take special attention while in use and laser safety goggles are always necessary.

You should always take a clear check to find if there are any flying objects or other objects, a false pointing of laser pointer might cause desperate damage, and you certainly obliged to your fault. It is never too much to pay enough attention while pointing a portable laser.
