Putting it simply, Raman spectroscopy involves shining monochromatic laser light onto a sample of material. The molecules in that substance vibrate in response, scattering the light in a unique ...

Now i was thinking, some lasers emit monochromatic light, would it be possible to take a colour accurate picture of that laser's beam, and print it?<BR><BR>For example, you have a 540nm green laser.

Macquarie University researchers have demonstrated a technique to dramatically narrow the linewidth of a laser beam by a factor of over ten thousand – a discovery that could revolutionise quantum ...

This study presents a multi-junction PPC with over 50% efficiency, addressing key challenges in optical power transmission ...

Not every laser, of course, but in the 1980s, the most common lasers in commercial applications were probably the helium-neon laser, which used a couple of mirrors on the end of a chamber filled ...

Helium-neon lasers may be little more than glorified neon signs, but there’s just something about that glowing glass tube that makes the whole process of stimulated emission easier to underst… ...
