A wavelength locking method and a laser are used for realizing wavelength locking without using a polymer with a negative thermo-optical coefficient. The wavelength locking method includes: the target wavelength aligned with the reference point is taken as the output wavelength (601), the reference point is the only Valley corresponding to the target wavelength in the periodic spectrum of the wavelength locking standard device, and the periodic spectrum is the spectrum not affected by temperature change; the laser determines the actual optical power difference (602) by detecting the output wavelength; Whether the difference is equal to the maximum optical power difference (603), the maximum optical power difference is the power value corresponding to the target wavelength; if not, the laser determines the wavelength offset (604) according to the actual optical power difference and the maximum optical power difference, and the wavelength offset is the deviation between the output wavelength and the target wavelength affected by the temperature change; the laser determines the output wave according to the wavelength offset. Long correction to target wavelength (605).
