Abstract

Exemplary method and configuration for a frequency conversion can be provided. For example, such method and configuration can use at least one transition metal dichalcogenide (TDM) crystal (which can include one or more MoScrystals, which can be stacked). For example, it is possible to providing at least one radiation to the at least one TDM crystal so as to generate a resultant radiation. Resultant information can be generated by measuring difference frequency and a second harmonic generation (SHG) from the resultant radiation provided from the TDM crystal. The frequency conversion can be obtained or achieved by providing a measurement of a SHG coherence length based on the resultant information.
