摘要： We demonstrate a non-crossover sub-Doppler dichroic atomic vapor laser locking (DAVLL) in selective reflection scheme, which allows us to obtain a modulation-free laser locking with wide tuneable range. The dependence of peak-to-peak amplitude, tuneable range and the slope near the zero-crossing point of error signal on the frequency shift induced by the magnetic fields are studied. The adjustable error signal by the varying external magnetic field can offer the laser locking from the order of tens MHz to hundreds MHz. The ultimate dither of locked laser frequency is less than 0.5 MHz. The square root of Allan variance of the error signals reaches a minimum of 3×10-10 for an averaging time of 130 s.
