Hi all,
I'm currently trying to a pulse which first send out 24 V for 5 ms pulse width and stay 10 V for 10 ms pulse width after that in order to control the laser through beam shutter . Please refer to the attached drawing. The 24 V is to give the beam shutter a big push to open up quickly in order to let the laser go through, but, continuously passing 24 V into the beam shutter will fry it. So, 10 V is required to hold the beam shutter open for 10 ms.
I created 2 pulses with 2 different set of circuit and tried to combine them together. However, I'm not sure how to combine both pulses together as one and sent into a load, the beam shutter. I tried to connect two collectors of each TIP102 and send in to a beam shutter as a load at one end, on the other end, I connect one to 24 V source and another one to 10 V source. It turned out incorrect.
Can someone please tell me what's the best way to combine 2 pulses together before entering the load or correct the circuit in order to perform as required. Thank you!
