Laser might cause a fire which is why they don't use it. I think best method is to simply mimic the human hand motion. You grab the berry but you put your two fingers over the stem and then pull down on the berry until the stem disconnects. This method might be even superior to the scissors method since you won't need to replace the scissors due to dullness.
