An optical cavity is combined with non-linear optical crystals and a laser source to generate light radiation at a frequency about 1.5 times the frequency of the initial laser source having a wavelength ⅔ that of the initial laser source. The optical cavity comprises mirrors with relatively high reflectivity for optical radiation at a frequency of F / 2, superior transmission for radiation at a frequency of 3 / 2*F for extracting the final radiation and mirrors with relatively immediate or high reflectivity, or generally high transmission for radiation at frequency F. The effective optical length of the cavity is precisely tunable by acting on at least one of the mirrors that form the cavity. The optical cavity contains at least two non-linear optical crystals: at least one of which satisfies the phase-matching-quasi phase-matching-condition for non-linear conversion F 2*F / 2, and at least one of which satisfies the phase-matching—or quasi phase-matching-condition for non-linear conversion F+F / 2? 3 / 2*F. The length of the optical cavity, and its resonance modes, are actively stabilized such that the only process of frequency division is that by a factor of 2.

A global positioning system (GPS) log with low power consumption has an antenna, a GPS module, a power control module, a main control module, a power adjusting unit and a memory. The main control module is connected to the GPS module and the power control module to retrieve the computing results of the GPS module and controls the power control module to periodically provide power to the GPS module according to a predetermined and variable power providing period. The power adjusting unit is connected to the main control module, analyzes the computing results of the GPS module and assists the main control module to adjust the power providing period. Since the main control module automatically adjusts the power providing period, the GPS log does not deplete unnecessary power on the GPS module. Therefore, the power consumption of the GPS log is reduced and the GPS operates longer.
