Russian Researcher Proposes New Spectroscopy Excitation Source

Facebook X LinkedIn Email
One difficulty with Cr4+ and Ti3+ lasers is the delay between pumping and lasing pulses. This delay poses problems for spectroscopy, which needs an excitation source that has high temporal stability with respect to the pumping pulse position. Now a Russian physicist has published results that point to an alternative excitation source: a diode-pumped LiF:F2+. The laser offers low-threshold reliability and tunability between 820 and 1200 nm. Because of the high gain of the F2+ center in LiF, there is almost no delay between the pumping and lasing pulses and none between pulses of...Read full article
