摘要： A laser assembly and a method for controlling light output thereof are presented. The laser assembly comprises a semiconductor laser diode having an active region and its associated electric current driver. The electric current driver is controllably operated to excite said active region to induce a certain electric current profile therethrough. The electric current profile corresponds to a desired emission profile from the laser assembly and a desired over heating profile of the active region of the laser diode, while maintaining predetermined temperature range of said active region of the semiconductor laser diode.
