thank you guys. i just needed a 5000 photons per 30ns pulse illumination source to be get it registered on the CCD camera.
and your feedbacks save me a lot work i guess.
Thanks for the feedback. i appreciate that. i was able to detect optical response till 300kHz with my current system, and was not able to go higher that might be because of the reason you mentioned. however my ultimate goal is get an around 30ns pulse (repetition should not very high) to...
hi
i need a driving circuit for 500mW green laser pointer to run in pulsed mode as high as 20 Mhz. using some of the circuits found on Pulse Circuits for Infrared LEDs and Visible Diode Lasers. i was able to get as high as 500mA current. (used a signal generator instead). but apparently not...
