We propose a theoretical scheme for measuring a laser's wavelength. Within a one-dimensional harmonic potential well, the laser wavelength forming Kapitza–Dirac pulses can be measured by employing multipath interference of Bose–Einstein condensates. Utilizing the propagator method, we calculate the theoretical maximum sensitivity for measuring the laser wavelength without considering Bose–Einstein condensate's two-body interactions, estimated at 10−7. Numerical evolution of the Gross–Pitaevskii equation with Kapitza–Dirac pulses is conducted using the operator-splitting method, revealing that lesser attractive and repulsive interactions diminish the measurement sensitivity.
