“…The inset in Figure 9 We have additionally experimentally studied the amplification of a single frequency, narrow linewidth (~10 kHz) FBG-DFB using a representative TDFA with lower output signal power [28]. Figure 10(a) shows an experimental setup in which we measured the heterodyne laser linewidth of two single frequency FBG-DFB fiber laser sources.…”

We report the optical architecture, experimental performance, and simulated performance of polarization-maintaining CW and pulsed single clad Tm-doped fiber amplifiers designed to operate over a wavelength span of 1760-1960 nm. We highlight the potential applications of these amplifiers to quantum computing and quantum qubit experiments using 1762 nm light. Our amplifier exhibits 3 W CW output power and 20 W peak pulsed output power (2 MHz rep. rate, 10% duty cycle) at 1762 nm. Measurements of the wavelength response of the TDFA yield an experimental operating bandwidth extending from < 1750 nm to > 1920 nm. Simulations of the amplifier bandwidth indicate a 3 dB (50% FWHM) wavelength span of 1745 nm to 1980 nm (135 nm). Experimental output power and bandwidth results agree well with the simulations. The external noise figure for this amplifier ranges from 7.5 dB to 9.5 dB. No linewidth broadening was observed in a typical TDFA output when using a single frequency input laser source with a linewidth of 10 kHz. We discuss suitability and applications of the TDFA to 1762 nm enabled manipulation of optical qubits in trapped 133 Ba + ions.

“…Several configurations of THDFLs enable SLM operation, such as distributed feedback (DFB) [11] and distributed Bragg reflector (DBR) [12,13] structures with ultrashort cavities, as well as conventional linear or ring compound cavities with ultra-narrow-band filters. The amplified spontaneous emission (ASE) of thulium-doped fiber (TDF) or THDF falls within the range of 1.7-2.1 µm, with a center wavelength near 1900 nm [14][15][16].…”

A wavelength-tunable single-longitudinal-mode (SLM) narrow-linewidth thulium/holmium co-doped fiber laser (THDFL) was developed in this study. The lasing wavelength was determined by combining a phase-shifted fiber Bragg grating (PS-FBG) and a uniform FBG (UFBG). SLM oscillation was achieved by incorporating a dual-coupler ring filter with the PS-FBG. At a pump power of 2.0 W, the THDFL exhibited excellent SLM lasing performance with a stable optical spectrum. It operated at an output wavelength of ~2050 nm with an optical signal-to-noise ratio of >81 dB, an output power fluctuation of 0.15 dB, a linewidth of 8.468 kHz, a relative intensity noise of ≤−140.32 dB/Hz@≥5 MHz, a slope efficiency of 2.15%, and a threshold power of 436 mW. The lasing wavelength tunability was validated experimentally by stretching the PS-FBG and UFBG simultaneously. The proposed THDFL had significant potential for application in many fields, including free-space optical communication, LiDAR, and high-precision spectral measurement.

“…An important motivation of these research activities is to find out a suitable approach to achieve electrically pumped lasing in organic semiconductors. However, such designs with the organic semiconductor spin-coated on the top of a Bragg grating [11][12][13] or with the Bragg grating written into the organic semiconductor thin film [14][15][16] have problems of the low output power, large beam divergence, and low quality of the transverse mode in the far field, limiting practical applications of this kind of laser device.…”
