This will depend on many different factors, including the application you are considering for the laser. All colors and powers are great for astronomy or stargazing as well as many other purposes, so once you've determined the colors and wattage you're looking for, the next step is to consider design features. Factors such as key safety features, adjustable focal length, lens caps and other accessories should be considered to ensure that you choose the right laser for you. The manufacture of laser products falls into four categories according to the power of the beam. CD and DVD player beams fall into category 1 and are the lowest. green laser pointer belongs to the third category, industrial laser equipment belongs to the fourth category, the manufacture of laser products according to the power of the beam is divided into four categories. CD and DVD player beams fall into category 1 and are the lowest. Laser Pointers belong to category 3 and industrial laser equipment to category 4.

The apparent brightness of an illuminated spot depends largely on the wavelength of the emitted light. Most devices operate in the region of the red spectrum, where the sensitivity of the eye decreases rapidly as the wavelength increases. A device with an output of 650nm is about twice as bright as a device emitting the same power at 670nm, while a device with a output of 635nm is about twice as bright. However, high powered laser Pointers at shorter wavelengths are usually more expensive. This is especially true for green lasers, which are much brighter than red ones but still expensive. They involve diode-pumped solid-state lasers and frequency doublers. Because the frequency doubler's conversion is generally poor at low power levels, it takes hundreds of milliwatts of infrared light (typically 1064 nm) to generate a few milliwatts in a green environment; So batteries don't take long to get heavy.
