Silanna Semiconductor has created a laser driver IC that can squeeze a 400W quad EEL (edge-emitting laser) module into 80mm2.

[Les] from [Les’ Lab] has designed a driver for laser diodes up to 10 watts ... improving stability of the current regulation circuit, the PCB design requirements, and planning user interface ...

Thus, he talks extensively about designing the driver circuit with safety in mind ... that we should know what goes into operating a laser of such power. He explains the importance of choosing ...
