Locking a RIO PLANEX Laser to the Vescent FFC-100 Fiber Frequency Comb

The modern fiber frequency comb is a tool with incredible versatility, and a long list of applications both in the lab, and the field. One such application is the use of a comb to transfer the stability of one CW laser to another with a frequency difference which lies outside the bandwidth of typical photodetectors. To do this, the comb is locked to a stabilized CW laser at a convenient wavelength, and then a second laser is locked to the comb at a wavelength anywhere within its spectrum. In this application note, we will demonstrate the second part of this setup with the stable lock of a RIO PLANEX 1550nm narrow linewidth laser to the Vescent FFC-100 Fiber Frequency Comb using the Vescent D2-135 Offset Phase Lock Servo.
