I'm looking for recommendations for any type of sensor that can detect a short pulse from a laser. I'm currently using an LDR but it only works mostly at night and not during the day. Also it will only work with a laser pointer rather than a very short laser pulse such as the one coming from iTarget Pro laser dry fire training. Any recommendations will be really appreciated. I have a video but is too big to upload it here.
Define "short"
Not sure how short is the pulse, maybe half a second or less. The pulse comes from a laser bullet.
The pulse comes from a laser bullet
Not a pulse rifle?
I'm using an arduino with other components. It is like a robot that runs on 2 wheels. see photo attached
No, it is not a pulse rifle. Please see photo attached.
You can try something like this:
A Google of LASER Sensor should bring up those plus plenty of others.
The problem with LASER Cartridges and dry fire is they show you how bad you shake. When you see the dot shaking you try to concentrate and then shake more. 
Just kidding.

Thank You Ron! I will check the link. By the way with this laser bullet you do not see the laser at all until you fire then you can see where you hit if you look at the target right at the moment you dry fire.

Years ago I played around a little with the rifle cartridge versions. They turned on on bolt closure or in the case of semi-auto when the bolt was in the home position. They were mostly used for bore sighting and used a red LASER.
Good luck with this.
