Why blue laser pointers are much more expensive than green laser pointers

One of the most obvious differences between a blue laser pointer a green laser pointer is the price. A blue laser pointer from 10 MW to from $ 700 compared to the price of the equivalent pointer 15mW green laser costs $ 100.

Not that blue laser pointers are more expensive. Blue laser modules, OEM laser and laser laboratory also much more expensive than their counterparts in green. The reason for these price differences are important processes used to generate the laser beam, the components used in manufacturing levels.

generation process Manga

The blue and green laser pointers use a 808nm diode pump giving infrared light used to pump the same type of crystals. The crystal is pumped in turn, raise the light in the infrared spectrum. The difference between blue and green laser is the layer of glass optical pumping and the type of measurement of infrared light produced by these crystals.

The crystal is pumped with a laser pointer The Greens have an optical coating which makes the crystals are mostly 1064nm infrared light is frequency doubled by another crystal 532nm green light. The crystal is pumped into a blue laser pointer is another layer that makes the crystals are essentially 946nm infrared light is frequency doubled by 473nm light another drink.

Components

The production process of the 1064 the light is much more efficient than making light of 946nm blue laser pointers if you need a large pump diode to produce the same power. The large diode pump laser pointers blue is more expensive. The frequency of double glass rear blue lasers are rarer and more expensive than green laser pointers.

Production volumes

Green laser pointers have a better visibility of blue laser pointers and had fewer problems with temperature at higher power levels. This means that green lasers are used a larger number of applications such as astronomy, stressing, engraving and marking and are manufactured in large quantities. pointers blue laser, on the other hand are much more limited their application and are produced in much lower volumes. Like any other product, the higher the volume produced, the more expensive the product.
