【Abstract】 A high power, narrow linewidth laser diode (LD) as one of the key elements of Integrated Optical Rotation Sensor (IORS) is studied. Both theoretical analysis and experimental research show that the light source′s linewidth of the IORS should be less than 300kHz to achieve 1(°)/h resolution for rotation sensing. Furthermore, a LD pumping Nd:YAG laser with high power, narrow linewidth and a LD with fiber bragg grating external cavity (FBG\|LD) are applied in the experimental setup of IORS, respectively. The measured finesse of the resonator coincides is as same as the calculated value. \;更多还原
