“…Important to note is that in the Cr:ZnSe laser setup of C.H. Zhang et al where a volume Bragg grating was inserted just to establish narrow-linewidth operation without wavelength tuning [19] the corresponding power loss was also significantly larger than the power loss we observed for our resonant grating (540 versus 70 mW). Of course, the comparison we made here with the results for the metal tuning grating of I.S.…”

International audienceWe report the first demonstration of resonantgrating- based laser wavelength tuning in the mid-infrared spectral domain and with Littrow mounting of the grating. We show for a mid-infrared Cr:ZnSe laser that this tuning technique is much more wavelength selective than prism-based tuning, while inducing very low cavity losses (around 2%), which are at least two times smaller than in the case of a standard metal grating. Furthermore, the resonant grating allows tuning the Cr:ZnSe laser over as much as 400 nm around a center wavelength of 2.38 μm. This shows the potential of employing Littrow-mounted resonant diffraction gratings for controlling and tuning the emission wavelength of lasers emitting in the mid-infrared spectral domain and other wavelength regions

“…Apart from the applications in the fields of light detection and ranging (LIDAR), frequency metrology, time-resolved spectroscopy, laser microsurgery, plastics material processing, and free space optical communication [1,2], ultrafast laser sources around 2 µm with high peak power are gaining more and more attention as potential pumping of solid state lasers such as Cr 2+ :ZnSe [3] and optical parametric oscillators (OPOs) for the mid-and far-infrared spectral regions. Based on the above listed wide potential applications, wavelength tunable laser sources near 2 µm are potentially of high interest.…”

A passively mode-locked Tm,Ho:YAP laser around 2.1 μm wavelength employing a semiconductor saturable absorber mirror is demonstrated. Stable continuous wave mode-locking operation was achieved at variable center wavelengths of 2036.5 nm, 2064.5 nm, 2095.5 nm, 2103.5 nm, and 2130 nm, respectively. Pulses as short as 40.4 ps were obtained at 2064.5 nm with a spectral FWHM of 0.5 nm at output powers of 132 mW and a repetition rate around 107 MHz. A maximum output power of 238 mW was obtained at 2130 nm with a pulse duration of 66 ps.

“…In the literature it is possible to find the crystals based on chalcogenide host with various transition metal dopants as promising mid-IR laser materials [3,5,6]. In the last twenty years such materials as Cr:ZnSe, Cr:ZnS, and Cr:CdSe were proved as the active media for the tunable lasers in the range of 2.0 -3.5 µm [7][8][9][10][11][12][13][14][15][16][17][18]. For the 3 -5 µm region, divalent iron ion (Fe 2+ ) in the same chalcogenide -ZnSe material was used.…”

Laser properties of Fe:Cr:Zn1-xMgxSe crystal for tunable mid-infrared laser sources

The characterization of new gain‐switched Fe:Cr:Zn1–xMgxSe laser working at the room temperature and its comparison to Fe:ZnSe laser was performed. The laser oscillation behavior, generation efficiency and output wavelength tuning possibilities were demonstrated. It was shown that the absorption and luminescence spectra of Fe:Cr:ZnMgSe crystal are shifted towards longer wavelengths in comparison with Fe:ZnSe active material. The difference is approximately 300 nm and it corresponds to measured absorption and emission spectra. The maximal Fe:Cr:ZnMgSe laser generated energy and the slope efficiency with respect to the absorbed energy were 200 µJ and 4.5%, respectively.
