Abstract :
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 barm labeled cyan fluorescent protein (CFP) as a sample for the floresence microscope.
