The invention provides a signal time-delay circuit, a relaxation suppression oscillation device and a laser. The circuit comprises a signal shaping unit, a first time-delay unit, a first time-delay control unit, a second time-delay unit, a second time-delay control unit and a signal output unit which are connected in sequence, the signal shaping unit comprises a comparator; the first delay unit comprises a first diode, a first potentiometer and a first capacitor; the second delay unit comprises a second diode, a second potentiometer and a second capacitor; the delay duration of the first delay unit is equal to the delay duration of the second delay unit. According to the embodiment of the invention, after the input signal is delayed, the output signal keeps the same pulse width, the workload of debugging such as software and hardware calibration and matching is reduced, and the production efficiency is improved; the delay time is not influenced by the width of the input pulse, and the complex problem of using
