What is an infrared laser module?

Infrared(IR) laser is electromagnetic radiation (EMR) laser with wavelength longer than other visible lasers and shorter than radio wave, which covers a wide range wavelength of 700nm to 1700nm. A typical used infrared laser module consists of a infrared laser diode, a electric driving circuit board, a collimating lens. Configured with high duration and ultra compact structure design and good thermal emitting system, it always enables high level of beam stability, competitive price, and high capability.

What is a violet laser module?

Violet laser module emits laser light within violet spectrum regions between 390nm and 419nm, which gets the most commercially common available wavelength of 405nm violet light. It gets the shortest wavelength than formally available blue, green, red lasers among visible optical spectrums. It is a short enough wavelength to caused fluorescence in chemical experiment.

What is a blue DPSS laser?
Unlit the time of 2006, blue laser pointer is available on the laser market. Being made with the same type of laser light source indication as a 532nm green DPSS laser, it gets the most commonly blue laser light at a wavelength of 473nm. Blue DPSS laser is produced by frequency doubling of 946nm laser radiation through a diode pumped Nd:YAG or Nd:YVO4 crystal. 946nm wavelength laser makes efficient transition into 473nm blue laser radiation, which is making efficient job for lab experiment, scientific experiment for those of labs and institutes etc.

How to get a green laser module?

It is a typical special laser light source in type of doubled YAGs. 532nm green DPSS laser is originally obtained via infrared laser diode at about 808nm or 980nm wavelength. After pumps a small slab of glass or yttrium aluminum garnet (YAG), doped into neodyminum, to produce a 1.06 micron laser beam, sent into a lithium niobate crystal at a certain angle to cause a nonlinear optical process, and converted to a green photon via two infrared photons at wavelength of 532nm.

What is a green diode laser?

What is a green diode laser?

Green diode laser is projecting green spectral regions, roughly covering wide wavelength range of 500nm to 570nm, including 505nm, 515nm, 520nm. It is a laser diode that uses semiconductors, not the same as formally used 532nm green DPSS laser system. Direct diode based green laser diode module and green laser pointer are offering high level of laser beam stability, low noise, and high modulation etc.

Where can I buy a green laser pointer?

Where can I buy a green laser pointer?

While, before choosing an ideal green laser pointer, you have been surfing online or seeking for suggestions with someone else. A qualified laser pen should not only get reliable quality, but also reliable after sale services. Low price is not the only one choice for users. It should be designed with elegant and durable shell, long lasting and good quality green laser beam and green laser dot emission of laser beam aperture.
