Abstract
A diode laser output power system controlled by microprocessor is presented.The work current of diode laser is controlled by stable current source and light power feedback.To make diode laser working temperature invariant,the temperature control technology of semiconductor is applied.In the same time,a series of protecting measure are adopted.Therefore,the system can obtained a continuously adjustable optical power output with high accuracy and stability.
