We present a thulium-doped single-oscillator monolithic fiber laser emitting successively at three wavelengths, especially at unusual long wavelengths as 2.09 µm and even at 2.12 µm. The 793 nm core absorption of 8.42 dB/m allows for achieving a sl

International audience; A single-oscillator monolithic thulium-doped fiber laser in which the 793 nm core absorption of 8.42 dB/m allows emitting 193 W (46 % of slope efficiency) at 2.09 µm is presented. An 8 •-cleaved angle of the fiber facet sup

We present the optimization of a 2.1-µm continuous wave monolithic single-oscillator laser by adapting the Fiber Bragg Grating (FBG) reflected wavelength to the maximum gain wavelength of the Tm3+, Ho3+-codoped fiber. Our study examines the power an

Non-planar image-rotating OPO ring resonators necessitate polarisation compensation in contrast to their planar counterparts. This is essential for maintaining phase matching conditions for non-linear optical conversion in the resonator during each c

We analyze theoretically and experimentally the performance of an OPO device with ZGP crystals in two types of nonplanar resonators that are of particular interest for ns-pulsed sources of high-power or high-energy mid-IR radiation.

We discuss main challenges in scaling up the output power of high-repetition-rate optical parametric oscillators (OPOs), that are nowadays the most promising technology to reach the level of output power of a few tens of W with reasonably good beam q

Fiber lasers emitting at wavelengths around 2 μm in continuous wave (CW) regime are promising sources of laser radiation for both civil (surgery, spectroscopy, lidar) and military applications as infrared countermeasures or laser weapons [1] . Optim
