The pulse laser is rubbish, unlike the laser from the original game. Which is odd now that I think about it. Anyhow, you should really avoid combat until you get a beam laser.
The 'angle 45 degrees and get off the space lanes' trick is pretty useful here, so you can avoid things until you get better kit.
