Here are some lazer types from Time Raiders. I am tooting my own horn here (Dr. Doom toots as he pleases) as I tried to make an example of every possible thing. It might as well be "Tech Demo Raiders." The drilling lazer fires rapidly with low damage to monsters. Use that as a base. I believe the time units are in game ticks here, which is 25 ticks per second. Distance units translate to 40 per tile, so 1000 is well over 20 tiles. You can move the camera very far away and hit things across the map, but the laser stops rendering after 700-800 units as the vehicle is culled for being too far from the camera.
Standard hand lazers are handled differently. Their entries in WeaponTypes { defines their shot behavior but does not affect damage. Damage is defined in the monster entries. Go to RockMonster { and compare the values to the ones below. In TR, pusher beams are the main weapon as you can adjust their range and they are not affected by the Infinite Crystal Drain Glitch. Freezers can have increased range, too. You can't really adjust the range of LaserShot (the one-hit kill laser). I've tried and raiders will deliberately fire just outside of its max range every time.
The handheld shot weapontypes. RechargeTime is pointless as rounds-per-minute is defined by the shooting animation. I made a shooting animation that's only five frames long and the raider fires its weapon five times per second under optimal conditions (multiple monsters need to be nearby or it doesn't fire quickly for some reason). I have not found a way to make shots go faster, but accuracy improves if you edit the firing animations so the shot comes out earlier. The rapid firing raider is very accurate since it fires on frame 2 or 3 of its animation. Standard raiders shoot on frame 14.
