Why Blue Laser pointers are much more expensive than green laser pointer

One of the obvious differences between a blue laser pointer and a green laser pointer is the price. A 10 mW blue laser pointer cost $ 700 to the price of the equivalent of 15 mW green laser, $ 100 cost.

It is not only blue laser pointer, are expensive. Blue Laser Module, OEM laser and laser laboratory are much more expensive than their green counterparts. The reason for thislarge price differences are the processes used by the laser beam to produce, using components for production volumes.

Beam generation process

Both green and blue laser pointer, a pump diode, crystals are 808nm infrared light type, the same is used for the pump. The crystals pumped in turn, to give light in the far infrared spectrum. The difference between blue and green laser is the optical coatings on the pumped liquidCrystal size and type of infrared light produced by these crystals.

The crystals pumped green laser pointer pointer have a coating that causes the optical crystal that usually give 1064nm infrared light, the light is 532nm frequency doubled by another green crystal. The crystals pumped blue laser in a different lining , which causes the crystals to give out most 946nm infrared light, which also doubles the frequency of a crystal structure different 473nm Light.

Components

The production process of 1064nm light is much more efficient 946nm light as blue laser pointers need a large pump diode to produce the same power. The diode pump laser pointer makes biggest blue expensive. The frequency doubling crystal blue laser pointers are rare and expensive than those in green laser pointer.

Production volumes

> Laser Pointers Greens have a better view as blue laser pointer and have fewer problems with performance at high temperature. This means that green lasers are used in astronomy as a greater number of different applications and see how, burning, and signaling and are produced in great quantity. Blue laser pointer on the opposite side are much less in their application and produces in much lower quantities. As with anyProduct, the lower the quantity produced, the more expensive the product.
