Star Wars Blasters aren't lasers though. They've been described as being plasma cannons shootings bolts of plasma made from a high energy gas and shot out at the target. Thats why these bolts get deflected by non-reflective armours and bounce off lightsabers. There are Artilery blasters that travel a balistic trajectory which would be impossible with a laser. Since the blaster shoots plasma which is matter, Kylo can "Catch" it with the force.
