Abstract
A wavelength locked semiconductor laser module has at least one of semiconductor laser of the laser arrays and a heater and/or cooler configured to vary a temperature of the semiconductor laser(s). A phase shifted wavelength locker is configured with wavelength locker temperature sensor and microprocessor to control of the wavelength of the semiconductor laser of the laser arrays instantaneously with absolute precision.
