Tunable mid-infrared (IR) lasers attract significant interest for a number of advanced applications, for example, the structural analysis of biomolecules, such as protein and sugar chain, atmospheric remote sensing, the monitoring of poisonous gases and molecular treatment based on a molecule-structure change. In particular, a tunable mid-IR laser exhibiting high-speed wavelength tuning on the time...
In this study, we achieve extension of electronically tuned wavelength region to the mid-infrared region with difference-frequency generation (DFG) of the two wavelengths oscillated Ti:sapphire laser.
In this work presents a picosecond pulsed Ti:sapphire laser pumped with a frequency-doubled LD-pumped cw Nd:YVO4 laser and intracavity second harmonic generation (SHG) of picosecond pulsed rapid and random wavelength tuned Tksapphire laser. The laser allows the tuning range from UV to blue with picosecond duration. Moreover, the paper demonstrated a pumping of fluorescent proteins (FPs) using the...
We have demonstrated broadly tunable mid-infrared generation from 5 mum to12 mum by difference frequency generation pumped with an electronically-tuned-Ti:sapphire laser. Rapid- and random-access of wavelength is realized in the mid-infrared region.
