2014 has started with the arrival of our pulsed laser system – a Surelite Nd:YAG laser which pumps a Sirah pulsed dye laser.

Ps Spectroscopy lab, January 2014. Optical table and pulsed dye laser now installed.

We will use this dye laser for driving electronic transitions in Ps, such as the 1s – 2p transition at 243 nm. The dye laser uses coumarin 102 as the gain medium, lasing at 486 nm, which is then doubled in BBO.
