The early Laser pointer (HeNe) HeNe gas laser produced a laser with a wavelength of 633nm, usually 1mW. The cheapest laser pointer uses a deep red laser diode with a wavelength close to 670/650nm. The more expensive diodes use red and orange 635nm ...

For example, a blue Laser pointer with a specific wavelength of 473 nanometers usually has the same basic structure as a green laser. Many factories started producing blue laser modules, mass storage devices, and laser pointers in 2006. This is a ...

The blue Laser pointer can also directly generate indium gallium nitride semiconductor to generate blue light without frequency doubling. There are (447±5 nm) blue laser diodes on the market. The device is bright, the same as a violet laser diode ...
