a vial and a laser, part II
April 9, 2008 at 10:41 am | sam | everyday scienceSome people enjoyed the last installment, at 488 nm. Now we have another picture with a 532-nm, diode-pumped, frequency-doubled Nd:YAG laser:
The red fluorescence in the cuvette comes from a red-emitting DCDHF fluorophore (the last one was a green-emitting version).
