Can a blue laser diode be connected to a standard red laser diode driver?

Answer:

Most likely not. Laser diode drivers have to maintain a certain injection current for stimulated emission. Materials and structures used for red lasers are well refined and are efficient. Blue laser diodes are relatively new to the field and require higher current densities to maintain threshold, simply because the materials needed to emit blue light are difficult to work with (GaN). So, my guess is NO.
