“…In particular, for frequency-tunable, high-power, and low phase noise microwave or millimeter-wave generation, a switchable dual-wavelength fiber laser is considered to be a desirable candidate because microwave generation in this way does not require a high-quality frequency-tunable microwave reference source, and the system cost and complexity is therefore reduced [5,6]. Meanwhile, a single polarization laser can be applied in nonlinear frequency conversion, interferometric fiber sensors, pumping of active crystals and optical parametrical devices [7].…”

A single-and dual-wavelength switchable polarized Yb-doped double-clad fiber laser around 1120 nm based on a pair of fiber Bragg gratings (FBGs) is demonstrated. The polarization-maintaining (PM) linear cavity is composed of a double clad PM Yb-doped fiber (YDF) and a pair of PM FBGs. The laser can operate in stable dual-wavelength or wavelength-switching modes due to the polarization hole burning (PHB) and the spatial hole burning (SHB) enhanced by the PM linear cavity. In dual-wavelength operation, the two orthogonally polarized wavelengths are centered at 1118.912 nm and 1119.152 nm, with an interval of 0.24 nm and a signal to noise ratio (SNR) of 35 dB. The maximum output power is 14.67 W when the launched LD pump is 24 W corresponding to an optical efficiency of 61.1%. The lasing lines switchover may be realized by adjusting the polarization controller (PC) fitted in the cavity. The two single-wavelengths are 1118.912 nm and 1119.152 nm. When the injected LD pump is 24 W, the highest output powers are 7.68 W and 8.64 W corresponding to optical efficiencies of 32% and 36% respectively. The spectral linewidth of the lasing lines are 0.075 nm and 0.07 nm, and the average numerical values of PER are 20.3 dB and 19.9 dB, respectively.

Polarization investigation of the emission spectrum of Nd ions at the 4 F 3/2 → 4 I 11/2 transition in the b-cut Nd 3+ :YAlO 3 crystal showed that this gain medium is promising for multiwavelength laser operation. A diode-pumped continuous-wave Nd 3+ :YAlO 3 laser with an intracavity retardation plate and a dichroic output coupler demonstrated dual-wavelengths operation at 1064.5 & 1072.6 nm and 1072.6 & 1079.5 nm, as well as triple-wavelengths lasing at 1064.5 & 1072.6 &1079.5 nm. Low intra-cavity losses in the retardation plate allowed achieving a high laser efficiency close to that of a single-wavelength laser. The output power of the triple-wavelength laser reached 1.75 W under a pump power of 6.7 W with a slope conversion efficiency of 32.3 %.

Dy3+ doped and Dy3+/Nd3+ codoped LaF3 single crystals were successfully grown by the Bridgman-Stockbarger method in a self-made medium frequency furnace. The crystal structures of LaF3 were investigated, and their geometry optimizations were carried out. The electronic structures including band structure and density of state were calculated by using first-principles calculations based on density functional theory. The polarized absorption and emission spectra including near-infrared and mid-infrared fluorescence spectra were measured at room temperature. The energy transfer mechanism from Nd3+ ion to Dy3+ ion was presented, and the microscopic transfer parameters were calculated based on the phonon-assisted energy transfer theory. In summary, two promising routes of Dy3+/LaF3 crystal pumped by 1280 nm LD and Dy3+/Nd3+/LaF3 crystal pumped by 790 nm LD were proposed for a mid-infrared laser.
