Diode Laser Safety |
One should never look into the beam of any laser - especially if it is collimated.
Common visible red laser diodes, diode laser modules, and laser pointers produce 1 to 5 mW at various wavelengths between 670nm and 635nm. When collimated (as in the case of a module with internal optics or a laser pointer) the entire beam can enter and hurt the eye. Note that light at 635nm appears more than 5 times as intense as light at 670nm. Therefore, the apparent brightness of a source is not a reliable indication of its actual optical power output.
Much higher power visible and IR diode lasers are available and becoming much more common and affordable with the popularity of diode pumped solid state lasers (including green laser pointers which contain a high power IR laser diode). These represent even greater danger to vision and potentially even risk of heat damage or fire from a focused beam.
As the CE of Europe safety rule requests, lasers sold in EU territory must fall into two categories: class 1 <0.39mW, class 2 <1mW of collimated laser. And the FDA of USA allow the class 3A <5mW for the consumer products. As the detail safety rules would be different for different regions and applications, you also can contact EGISMOS for more information.

Introduction to Diode Laser and Laser Diode
The terms 'laser diode' and 'diode laser' somewhat can be used interchangeably. Usually we tend to use the term 'diode laser' when referring to a complete system or module. The 'laser diode' generally called as the device, refers to the combination of the semiconductor chip that does the actual lasing along with a monitor photodiode chip......more |

Typical Laser Diodes
The most common laser diodes of visible wavelength have 635nm, 650nm for red laser, and 405nm, 445nm for blue laser. As the green laser diode, it's still in developing stage and most of green lasers are made in a DPSS(Diode Pumped Solid State) technology......more |

Beam Characteristics of Laser Diodes
Unlike the helium-neon and other common gas lasers, the raw output beam from an edge emitting (also called Fabry-Perot or FP) laser diode is highly divergent and suffers from two asymmetries: astigmatism and an elliptical beam profile. The beam is also inherently linearly polarized......more |
