A stable dual-wavelength thulium-doped fiber laser operating at 1.9 μm using a short length of photonic crystal fiber (PCF) has been proposed and demonstrated. The photonics crystal fiber was 10 cm in length and effectively acted as a Mach-Zehnder interferometry element with a free spectral range of 0.2 nm. This dual-wavelength thulium-doped fiber laser operated steadily at room temperature with a 45 dB optical signal-to-noise-ratio.
已提出并演示了一种使用短长度光子晶体光纤（PCF）在1.9μm波长工作的稳定双波长掺铥光纤激光器。该光子晶体光纤长度为10cm，有效地充当了自由光谱范围为0.2nm的马赫-曾德尔干涉测量元件。这种双波长掺铥光纤激光器在室温下稳定工作，光信噪比为45dB。
