2014 Green Laser Pointer 5mW 532nm for Trade Shows

  

The Green Laser Pointer is the most visible laser color that produces a light that is 40-50x times the equivalent red laser pointer making them the first choice for enthusiasts looking to experiment with lasers. The reason Green Lasers seem more powerful is because the human eye is especially sensitive to the green light they emit.

 

*Greenn Lasers do not have IR filters and can be hazardous to eyes without Protective Eye Wear
*Safe for USA customers to purchase / FDA approves 5mW or less

History
Handheld laser pointers have caught people’s fascination ever since they were introduced to the public. Red laser pointers were the first handheld lasers to hit the market and as new technology developed it was possible to mass produce handheld green laser pointers. The year 2000 began a new millennium and also began a new realm of amateur laser enthusiasts. Today the technology has advanced to the point that the US military has weapon scopes that can blind targets from 2.5 miles or 4 kilometers away, using a 250mW Green Laser.

 

Science
Green Laser Pointers are much more complicated than a handheld red laser pointer; because the laser diodes in this wavelength range are not as common as the red laser diode.

 

The green laser pointer beam is generated using an indirect process that begins with a high-power infrared AlGaAs laser diode operating at 808 nm. The 808 nm light energizes a crystal with neodymium-doped yttrium aluminum vanadate (Nd:YVO4).

 

The Vanadate crystal is coated with a dielectric mirror on the diode side, that reflects at 808 nm and transmits at 1064 nm. The Vanadate crystal is mounted on a copper block to supply sufficient heat loss. The 1064 nm output is directed into a KTP crystal (potassium titanyl phosphate), mounted on a heat sink in the laser cavity resonator.

 

Our units utilize as a frequency doubler, and halves the wavelength to the desired 532nm that green lasers are viewed at.
