Or any device to transform a collimated laser into an incoherent collimated light source. To my understanding, I can maintain the coherence even if the laser is not collimated, an incoherent collimated light source would be composed of photons with different phase shifts but collimated.

Class 3B denotes lasers or laser systems that can produce a hazard if viewed directly. This includes intrabeam viewing or specular reflections. Except for the higher power Class 3b lasers, this class laser will not produce diffuse reflections. The beam from most HeNe lasers is already very well collimated even without external optics (unlike a laser diode which has a raw divergence measured in 10s of degrees). The divergence measured in milliradians (1 mR is less than 1/17th of a degree) is usually one of the tube specifications. $\begingroup$ For those thinking of comparing to a laser pointer, note that a bench-top HeNe device is usually very well collimated, while the Laser Emitting Diode (and the distinction between Laser LED and light LED is going to be problem going forward) used for pen-sized pointers is only pretty well collimated. $\endgroup$ – dmckee --- ex-moderator kitten Jan 26 '11 at 18:36 Or any device to transform a collimated laser into an incoherent collimated light source.

helium neon laser (the first continuous-wave laser), the semicon- ductor diode propagate, and it is therefore impossible to have a perfectly collimated beam.

In this case the orientation of the beam divergence needs to be specified.

HeNe lasers are preferred for many optics lab applications due to their ease of operation and low cost compared to other laser types. We measured the scattering intensity functions for HeNe-laser light of 80- to 100-mu m-thick human dental enamel slabs. The asymmetry factors were calculated to be g = 0.68 at 633 nm. By measuring the collimated beam attenuation, we determined the scattering coefficient to be s = 6.6 mm(-1).

The HeNe laser meets these needs because of its inherent simplicity and product maturity. Typical HeNe-laser lifetimes are measured in years. Product consistency is similarly good; thus, most HeNe lasers exhibit <0.5% unit-to-unit variation in beam diameter. In fact, this tolerance can be made even tighter in custom lasers by using more
