Pulse laser turret

The Pulse Laser Turret is a light Covenant ship to ship weapon. These pulse weapons are known to have been mounted on most covenant ships including artifact retrieval ships such as the Minor Transgression. The weapon can be used against starships but is also a likely candidate for a Covenant anti-aircraft weapon. Strangely enough, UNSC Prowlers are also mounted with pulse laser weaponry, but this version likely an independant UNSC development rather than reverse engineering of Covenant technology - pulsed laser technology was available to Humanity as early as 1960, and at least as early as the year 2000 in weapon form.

Physics
Before the weapon fires, it must first charge, during the charge a sphere of light energy forms around the charging weapon. After it is finished charging, it expels a cyan/purple beam of energy. According to the Halo novels and combat observations, a section of the ship's shields must be dropped for it to fire completely.

Damage
The weapon is said to have reduced the UNSC frigate Commonwealth's armor in sections three and four to a quarter which would mean (as frigates are known to have 60cm-thick armor) that a pulse laser salvo is capable of melting through 45cm of Titanium-A battle-plate in mere seconds. This means that pulse lasers pose a serious threat to UNSC frigates and smaller, lighter armored UNSC ships as it would only take one salvo to melt through parts of its armor. However, it is believed that larger UNSC ships with thicker armor would have to take multiple pulse laser salvos to show the same results. The Halcyon-class cruiser class can only resist 1-2 pulse lasers and Supercarriers can resist 2-3.
