It was only with the discovery of the Helm Memory Core that the various Inner Sphere powers could reproduce the technology. Like much of the advanced technology of the period, the ability to make pulse lasers was lost to the Inner Sphere during the Succession Wars. Pulse lasers were initially developed for use by the SLDF during the Star League Era(2450).

This allows subsequent pulses to reach the target area without being diffused by the vapor. Pulse lasers increase damage because they allow vaporized armor to dissipate from the location of damage. While offering an overall increased rate of fire, the heat output also increases accordingly. Pulse lasers differ from traditional laser weaponry, in that instead of firing one powerful beam, they maintain several laser beams fired off in quick succession. With the reintroduction of the Double Heat Sink, this technology has re-entered production and relevance, though on a small scale. Essentially two standard large laser systems combined to fire at once, the Blazer proved inefficient, combining high heat levels (200% of a Large Laser) with little increase to damage potential (50% increase over standard Large Laser). Nicknamed the Blazer, the Binary Laser Cannon was an experimental system widely regarded as a dead end technology. The large laser was prototyped in 2306 and reached full production in 2310. While they function identically to their production counterparts, they generate twice the heat when fired. Small and medium lasers entered full production in 2300.

These standard small and medium lasers are considered to be prototype systems in the year 2290. All standard lasers are typically grouped into three broad classes based on their range and damage potential: The various Clan militaries do not use standard lasers, having phased them out in favor of more advanced laser types. Standard lasers were introduced during the Age of War and cause damage by firing an intense beam of light at a target, flooding concentrated energy in the form of heat, which can melt material and overwhelm heat-sensitive electronics.
