Hello all,

I am a newbie and would like to know, if it is possible to construct a very high speed (bandwidth) power / voltage switch using a microcontroller or a driver to power a led or laser in the order of micro or nano seconds.

For example the microcontroller should power on the laser for few milli seconds and then switch it off. Please do post your comments.

Thank you.
 

I think most of the even small micro's can do that it's dependant on the clock speed of the micro but most is high enough a laser itself takes a few nano sec before it start lashing out light you can get micros that will easily do this.small pic micro's are cheap an easy to learn.
 
hi
if it's just switch on/ off for some microseconds, any controller will do.
if the controller is only to switch on/ off for some microseconds, any controller will do
for the above applications, use some logic circuits, which can perform better than controller.
if the controller should do something else and control the on/off, it depends on a lot of things

thanks to two both, can you please give simple one or two examples or names of the micro controllers or the logic circuit. Thanks a lot once again to you.
 

may be this ic can help you..
