“…Optical fiber for laser, or fiber laser, with its high stability, reliability, thermal resistance, and high beam quality, has attractive applications in sensors, communication, instrument testing, and high-resolution spectroscopy [1]. Recent advancements in optical fiber laser has led to the development of dual-wavelength fiber laser (DWFL) operation, particularly in applications such as microwave photonic filters [1], microwave carriers [2], and high bit-rate pulses [3]. Therefore, the operation of DWFL in optical fiber laser is highly beneficial and has naturally gained interest among the optical research communities.…”
