Electrical Lasers
All laser facilities such as NIF, Omega, Titan, Trident, Vulcan, HELEN, Orion and LMJ use little diode lasers or desktop laser basically to start it off and then use rods made of glass (eg Nd:YAG) to give you the pulse - chemical lasers aren't much more powerful, indeed all of the above mentioned lasers are way more powerful than the ABL with Omega, Vulcan and Orion, for example, being a billion times more powerful owing to the fact that they are petawatt systems.
Granted all of the above systems are pulsed, not CW like the ABL, but certainly 'electrical lasers' are there.
