What was the cause of the blue laser pointers much more expensive?

Both blue laser pointers and green laser pointers use a pump diode that gives out infrared 808nm light that is used to pump the same type of crystals. The pumped crystals in turn give out light in the far infrared spectrum. The difference between blue lasers and green lasers is the optical coatings on the pumped crystals and the type of far infrared light produced by these crystals.
The pumped crystals in a green laser pointer have an optical coating that causes the crystals to give out mostly 1064nm infrared light that is frequency doubled by another crystal to green 532nm light. The pumped crystals in a blue laser pointer have a different coating that causes the crystals to give out mostly 946nm infrared light that is also frequency doubled by another crystal to 473nm light.

The process of producing 1064nm light is much more efficient than making 946nm light so blue laser pointers need a large pump diode to produce the same power. The larger pump diode makes blue laser pointers more expensive. The frequency doubling crystals in blue laser pointers are rarer and more expensive than those in green laser pointers.

It is not just blue laser pointers that are more expensive. Blue laser modules, OEM blue lasers and blue lab lasers are also much more expensive than their green counterparts. The reason for such a large price differences are the processes used to generate the laser beam, the components used that the manufacturing volumes.

Green laser pointers have better visibility than blue laser pointers and have less temperature problems at higher power levels. This means that green lasers are used for a larger number of diverse applications such as astronomy, pointing, burning and signaling and are manufactured in very high volumes. Blue laser pointers on the other hand are much more limited in their application and are manufactured in much lower volumes. Like any product, the lower the volume produced, the more expensive the product is.

When Titanium Houses Laser Diode Tightly

Ordinary green lasers are everywhere, but their limitations sometimes minimize their usefulness in varying environments. For example, the crystal and electric circuits would be eroded over time if the ordinary green lasers are operated at too humid environments. The incompetent heat transfer will easily make ordinary green lasers overheated after being turned on for a little while. Some green laser pointers are made to be too fragile to stand the shock and shake in normal use.

To make the breakthrough upon existing laser pens or portable alloy-made lasers are barely possible. The laser pointers and portable lasers need to be revoluntionized anyway, while it’s obviously difficult to keep the costs down, especially when the employment of all titanium strikes the engineers at jetlasers.

We all know titanium is a critical strategic metal used in aerospace, automobiles, prosthetics, architecture and sporting goods. Nobody ever did think of using it on laser pointer pens or portable lasers, right? After all, to most people, laser tech is such a cutting-edge technology that it takes a lot of money to get a high stability laser pointer itself.

Simply the use of titanium on green laser pens or portable green lasers can potentially shock most laser hobbyists. However, jet lasers or jetlasers company knows how to shock people better. People soon find themselves lost in a land of unique and revoluntionized all-titanium laser models.

The lasers are waterproof to 30 meters and will be free from any oxidation even it’s soaked in water for 3 years. The anti-shock feature is also surpising enough, and it will stay well even if it falls down from 14 meters’ height. We’ve tested the all titanium casing that equips the led, it works well after such intense “fall”.

It seems that time has come for everyone to have a almighty green laser pointer that can be used in all kinds of weather conditions.

Background Information

Partnered with the the biggest Titanium production base in northern China, Jetlasers also comes up with the patented military-grade pure titanium green laser pointer models(including laser dazzlers), which hits the market the moment it strikes the idealism of the universal laser world. A series of photonics exhibitions witness the rise of Jetlasers all titanium laser models, while more and more laser hobbyists have been enthusing about those rarest and robustest lasers in their collection and meanwhile they bring the good name of the unique portable laser products into the world.
