Is there anyone knows what the time-pulse width is of 50mW 445nm/450nm Blue Laser Module. What is the fastest repetition rate the module can be driven? Thanks.:thanks:

Lasers have an excellent on/off cycle usually in order of nano even pico seconds as for blue 445 nm will be about the same an article i got after a search ........

—The best transistors today can switch on and off hundreds of billions of times a second. But laser pulses can be more than 10 000 times as quick. Now researchers in Germany have used such ultrashort laser pulses to induce current with the same kind of frequencies—creating an electric switch with laser speed.

“Laser pulses are the shortest signal you can generate,” says Martin Schultze, a researcher at the Max Planck Institute of Quantum Optics, in Garching, Germany, who was involved in the work and is currently a visiting scientist at the University of California, Berkeley. “They are much faster than anything electronic.”
