| Abstract: | A high stabilization constant current source for diode laser is designed in this paper. The load characteristics, temperature characteristics, current precision and stability of the costant current source, which uses the principle of negative feedback to adjust and stabilize output current are analyzed. The measurement results show that the current stability reaches 10^-6. By using the laser, the D2-line in cell of natural Rubidium with 1.3 kPa buffer gas is observed. In addition, there are several functions in this driver, such as anti-surge-current, current interruption protection, over-current protection, etc. |
