Read our latest editorial in the January edition of Laser Focus World on hows state-of-the-art OPO technology delivers laser light for excitation-tunable tip-enhanced Raman spectroscopy. The unique tunale laser, delivering single frequency tunable light from 450 nm – 650 nm, allows excitation over this large range and the response is quite different depending on the wavelength.
