Sodium silicate solutions of modulus 3. The controller for provides separate inputs to the laser including a front mirror current controlling a front mirror and a back mirror current controlling a back mirror to control the laser and a voltage monitor, coupled to a gain section of the laser for monitoring a gain voltage of the gain section and providing input of the gain voltage to the controller. Moreover, the subject invention can facilitate inter-operability among a plurality of RAID adapters, to move array sets from one controller type to another.
