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.

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

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 ...

Light can only pass through the cavity when it is in resonance with the cavity. These have been around since 1899, so they aren’t that exotic.

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 ...
