“…Tunable sources near 2 μm are also of interest due to their utility in applications such as speckle-imaging [2][3], eye-safe differential absorption lidar [4][5], range finding [6], coherent Doppler wind lidar [7], and terahertz (THz) difference-frequency-generation (DFG) [8]. Wavelength generation in the 2-μm region has been achieved using Ho 3+ -doped, Tm 3+ -doped, or Tm 3+ :Ho 3+ co-doped fiber lasers [9][10], mode-locked Tm:CaYAlO4 (Tm:CYA) laser [11], near-degenerate optical parametric oscillators (OPOs) [12], and, more recently, intracavity OPOs in two-crystal walkoff compensation scheme [13]. Laser sources at ~2 μm and beyond are also necessary for pumping long-wave mid-infrared (mid-IR) OPOs and DFG sources based on non-oxide nonlinear materials such as ZnGeP2, AgGaS2, AgGaSe2 and quasi-phase-matched orientationpatterned gallium arsenide (OP-GaAs) [12,[14][15][16][17].…”

We report on the development of high-average-power nanosecond and picosecond laser sources tunable near 2 m based on optical parametric oscillators (OPOs) pumped by solid-state Nd:YAG and Yb-fiber lasers at 1.064 m. By exploiting a 50-mm-long MgO-doped lithium niobate (MgO:PPLN) as the nonlinear crystal and operating the OPO in near-degenerate doubly-resonant configuration with intracavity wavelength selection elements, we have generated tunable high-average-power radiation across 1880-2451 nm in high spectral and spatial beam quality with excellent output stability. In nanosecond operation, pumping with a Q-switched Nd:YAG laser and using an intracavity prism for spectral control, we have generated more than 2 W of average power in pulses of 10 ns duration at 80 kHz repetition rate in narrow linewidth (<3 nm), with M 2 <2.8, and a passive power stability better than 2.2% rms over 1 hour. In picosecond operation, pumping with a mode-locked Yb-fiber laser and using a diffraction grating as the wavelength selection element, we have generated more than 5 W of average power in pulses of 20 ps at 80 MHz repetition rate in narrow bandwidth (~2.5 nm), with M 2 <1.8 and a passive power stability better than 1.3% rms over 2 hours. The demonstrated sources represent viable alternatives to Tm 3+ /Ho 3+ -doped solid-state and fiber lasers for the generation of high-power radiation in the ~2 m spectral range.

“…Recently, different dualwavelength TDFLs approaches at the 2-μm wavelength band were reported. These configurations are based on fiber Bragg Gratings (FBG) [1]- [9], spatial mode beating effect [10]- [12], carbon nanotubes [13], photonic crystal fibers [14], and fiber interferometers [1], [15]- [17], among others.

“…Zhou et al proposed a stable dual-wavelength TDFL based on cascaded fiber Bragg gratings [6]. Soltanian et al achieved stable dual-wavelength operation of a TDFL operating at 1.9 μm by using a 10 cm length of photonic crystal fiber [13]. Nevertheless, most of the previously reported dual-wavelength fiber lasers based on TDF exhibit laser emission with wavelengths below of 2 μm.…”

Abstract-A tunable dual-wavelength thulium doped fiber laser is demonstrated experimentally. For the first time for the 2-µm wavelength band we propose the independent tuning of the generated laser lines based on fiber Bragg gratings and the use of a Hi-Bi fiber optic loop mirror for the fine adjustment of the cavity losses to obtain stable dual-wavelength operation. Dualwavelength laser generation with the laser lines separation in the range from 0.3 to 6.5 nm is obtained. The laser emission exhibits an optical signal-to-noise ratio better than 56 dB. Improved stability with output power fluctuations less than 1 dB is observed in dual-wavelength generation with equal power of lines.

A stable dual-wavelength Tm³⁺:Ho³⁺ co-doped fiber laser operating above 2 μm based on cascaded single-mode-multimode-single-mode (SMS) fiber structures is proposed and experimentally demonstrated. Based on the theoretical analysis of the transmission properties of the SMS fiber structure, two cascaded SMS fiber devices with different multimode fiber (MMF) lengths were used in our laser system, where one acted as a long-pass filter to suppress the competitive laser below 2 μm, and the other worked as a band-pass filter to select the specific operating wavelengths of the laser. Dual-wavelength operation of the fiber laser at 2002.8 and 2016.1 nm has been achieved in the experiment with a signal to a noise ratio up to 50 dB.
