Rather than using a single powerful beam, the Pulse Laser fires a series of rapid pulses. While increasing damage and decreasing the beam duration, Pulse Lasers generate more heat and have shorter ranges than their standard Laser counterparts. The Large Pulse Laser is the largest and does the most damage of the Pulse Laser family.
When compared to the standard Large Laser, the pulse version generates much more heat and weighs more, as much as a PPC. It also has a shorter effective range, roughly the same as the Medium Laser. In exchange, though, the Large Pulse Laser deals the greatest damage of any beam weapon, nearly as much as both versions of the PPC. Coupled with pin point accuracy and shortened beam duration, this weapon is favored by those who have tonnage to spare and wish to maximize their damage potential at close range.
