800 nm Laser

Most of the 800nm laser are 808nm infrared laser, here are two type of 800nm infrared laser: 200mw infrared 800nm laser and high power 400mw 800nm laser. 

800 nm laser pointer is infrared laser, it produces 800 nm laser. The 800 nm laser pointer is invisible laser, the 800 nm laser beam can't be seen by human eyes. However you can see the 800 nm laser dot, while the 800 nm laser shoots on some targets. You need to look at it carefully.  We usually call 800 nm laser pointer to 808 nm laser pointer. The beam size of some high power 800 nm laser pointer is about 1 cm across when it leaves the laser, and even with that high peak power, you only start to cause some serious damage when you focus it down to a mm or less

808 nm – GaAlAs pumps in DPSS Nd:YAG lasers (e.g. in green laser pointers or as arrays in higher-powered lasers)

Hair removal with an 800-nm pulsed diode laser.A total of 38 subjects were treated with a prototype of the 800-nm diode laser system. Fluences ranging from 10 to 40 J/cm(2) (mean, 33.4 J/cm(2)) were used and 1 to 4 treatments (mean, 2.7) were performed. Evaluation of hair loss was performed at least 4 months after the last treatment (mean, 8.7 months) by a blinded assessment of clinical photographs.
