A robust and compact blue optical frequency reference within blue region was designed. A 40-mW tellurium-stabilized single-frequency blue diode laser in external cavity was designed with an absorption spectroscopy method based on tellurium molecular transitions. Furthermore, the uncertainty of the frequency stabilization can be pushed to 2 × 10−9 at a 10-s integration time. In addition, the correspondence frequency instability was 1.3 MHz when the laser wavelength was 445.75 nm. This study indicates that high-stability frequency reference within the blue region can be achieved with an external cavity diode laser as opposed to the diode-pumped frequency-doubled solid-state laser.
