Best color laser pointer for dogs
Green lasers are much more expensive. This is because there are no green laser diodes and some technical efforts must be made to produce green. It requires two crystals, a special light-emitting diode and an extra filter. Using two crystals is also called frequency doubling. Additional components, plus their optimal alignment, result in additional costs. However, higher technical efforts have also made this type more sensitive. If such a laser pointer were to fall, it would most likely be unusable because sensitive optics could be damaged.
