Phase Stability/Wavelength Repeatability

In some OCT applications it is beneficial to have subsequent sweeps be at the exact same point in the interferograms.  This is typically referred to as phase stability, but could also be termed "wavelength repeatability."

Wavelength repeatability of ±2.5 pm span (peak amplitute) and 0.5 pm standard deviation has been confirmed for the all-semiconductor laser.
