I found this at the JoAT web site. It isn't canon, but it may help to explain the change from phase weapons to lasers.
From the Kaneda class destroyer entry:
quote: Kaneda was the first Starfleet vessel armed with dilithium-focused laser cannons. These lasers use a polished dilithium crystal to refocus and amplify the beam fired from a standard high-energy laser. The amplification creates a much more powerful beam than previously used before the advent of plasma and early phased energy weapons. Early tests showed dilithium to be too unstable when exposed to laser light but it was discovered that by modulating the frequency of the laser at very specific wavelengths a stable beam could be established through the dilithium crystal matrix. These lasers replaced the standard phase cannons of previous ships. This technology would be adapted and used for all Starfleet beam weapons until they were eclipsed by the phaser, an evolutionary merging of the early phase weapon technology and the dilithium-focused laser.
Seems to make sense...sort of?

Not to me...you can't really amplify EM radiation by passing it through a crystal...where's the extra energy coming from? Also, why do they have to use dilithium...they should've said lasers focused with the crystals they use in phasers, what do they call them, some Japanese phrase. Something-no-umi or something. The ones what with that there "rapid nadion effect."
