Abstract
To measure the absolute frequency of 127I2-stabilized Nd:YAG laser at 563.2 THz, a method based on a frequency difference generation (DFG) of two diode lasers operating in the near infrared region is proposed. A narrow free running spectral linewidth α-DFB diode laser operating at 281 THz (DL1) and a diode laser at operating at 192.6 THz (DL2). The diode laser DL1 is frequency doubled in a KTP crystal placed in a ring cavity of a finesse of about 100 and frequency of DL2 is doubled in a periodically poled lithium niobate (PPLN) crystal to phase lock the laser to the 385 THz rubidium optical frequency standard (OFS2).
