Improved rise and fall times for the driving pulses used to drive the laser in a laser writer are achieved by incorporating the sources of the READ, WRITE, and BOOST pulses in one ASIC chip and by having the pulses driving only one laser current driver stage which is held on by a READ signal, but which can be turned on harder when a WRITE and/or BOOST signal is applied, thus the delay associated with turning on the laser current driver stage is eliminated permitting higher writing speeds.
