Jul 10, 2010 · A He-Ne laser is quite monochromatic, but a bit red. A Green He-Ne is a bit expensive. Hg lamps give very monochromatic output through a series of wavelengths, Band pass filters are required to clean up the spectrum. Spectral emmision lamps can be purchased to provide monochromatic peaks.

Divergence The beam divergence of a laser beam is a measure for how fast the beam expands as it propagates in space. There are different quantitative definitions in the literature. According to the most common definition, the beam divergence is the derivative of the beam radius with respect to the axial...

The laser is a 10 mW JDSU µgreen 532 nm laser. It operates in single longitudinal mode (SLM). The laser has no beam shaping optics, and the beam is somewhat divergent. This is "fixed" with a beam-expander (the long black tube). I'm not sure this is essential. Everything was carefully aligned one component at a time.

But your flash only lights up for 100 ns, which is a bit more complicated. Normal lasers will not allow you to do that, in terms of switching on and off. So you need some kind of beam shutter for the laser -- but 100 ns seems still pretty fast, even if you have only a very narrow laser beam at shutter position. In principle this should be possible.

Green laser, blue laser, red laser, yellow laser, infrared laser and UV ultraviolet Laser systems are manufactured by CNIlaser. The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.
In 1978 the author described a laser beam expander that was unobscured, corrected for spherical aberration, coma, and astigmatism, and consisted of four spherical mirrors. It was not corrected for Petzval curvature, however; therefore the expanded laser beam would defocus slightly if the input...
