This paper describes the demonstration of a simple ytterbium-doped fiber (YDF) laser that utilized a short length of photonic crystal fiber (PCF) in a ring cavity and adjustments to the polarization state of an incorporated polarization controller (PC) to achieve a stable dual-wavelength output. The dual-wavelength lasing operation exploited the Mach Zehnder interferometer effect, and the laser output consistently achieved high power stability with a 0.8 dB fluctuation over a period of 30min This proposed setup has the capability for adjustable spacing of two lasing wavelengths from a minimum of 0.40 run to a maximum of 3.40 run, allowing for flexibility in dual-wavelength laser generation in addition to stable and reliable system features.
