In the green, the 522 nm fiber laser is built for neutral-atom tweezer platforms. Its low-noise, 1.5 W single-frequency output drives optical tweezer arrays and dynamic atom rearrangement, optical-lattice and dipole trapping, and light-shift engineering for species- or state-selective trapping, thereby maintaining trap depth and coherence across large arrays.
The 532 nm fiber laser, with ultra-narrow linewidth (<20 kHz), low relative intensity noise (-135 dBc/Hz>10 kHz), and polarization-maintaining, high beam quality output, is a compelling tool for quantum science platforms. At visible wavelengths, it enables resonant or near-resonant manipulation of atomic transitions (for species where green light is used) and can augment cooling, state preparation, or optical pumping steps. Its compact, stable, SHG-based architecture ensures that the delivered beams remain spectrally and spatially stable over long experimental runs, which is critical to preserving coherence in quantum systems.
In neutral-atom architectures that use green transitions (for example, in certain cooling or state-preparation stages), this 532 nm source can serve in optical molasses, polarization gradient cooling, or repumping. After initial laser cooling stages, the same laser can be used for state preparation or shelving pulses before qubit operations. Moreover, when combined with intense far-off-resonance trapping beams (from, say, 1064 nm), the 532 nm beams can create state-dependent potentials or light shifts to control internal states. The narrow linewidth and precise frequency control reduce off-resonant scattering and phase noise, preserving qubit coherence during manipulations.
For entanglement protocols or multi-qubit gates, 532 nm beams may drive Raman transitions or sideband couplings in hybrid schemes, or provide fast local addressing for individual qubits via tightly focused beams. Their stability limits technical noise that might otherwise degrade gate fidelities. In quantum sensing or metrology contexts, the 532 nm laser can also play a role in state readout, fluorescence excitation, or probing atomic transitions with minimal perturbation. Overall, a high-performance 532 nm fiber laser is a versatile enabler in quantum computing stacks, not just for cooling and trapping but for precision state control and readout.
The 556 nm fiber laser targets the ¹S₀ → ³P₁ inter combination transition of neutral ytterbium, the narrow "green" line of second-stage laser cooling. Its kHz linewidth and excellent power stability make it ideal for narrow-line magneto-optical trapping (MOT), cooling ytterbium atoms to the low-microkelvin temperatures needed to load high-fidelity optical tweezer arrays and optical lattices. These ultracold, tightly confined atoms are the foundation of neutral-atom quantum computing, quantum simulation, and state-of-the-art optical atomic clocks, where the 556 nm transition also supports precision spectroscopy and clock-state preparation. With its all-fiber architecture and IoT-enabled control, the 556 nm laser delivers the stability and reliability these demanding quantum experiments require.
The 649 nm fiber laser delivers 6 W of stable red light for trapped-ion and neutral-atom quantum computing. It supports single-qubit gate operations, signal readout, and repumping, and its low noise makes it well suited to mid-circuit measurement, where selected qubits are read out without disturbing the rest of the register.
The 770 nm fiber laser is designed for neutral-atom quantum-computing. Its narrow-linewidth, 2 W output supports repumping and metastable-state reset, state-selective readout, and the leakage- and erasure-detection steps that raise gate fidelity in array-based processors with enough headroom to feed several beam paths from one laser.
At the rubidium D2 line, the 780 nm fiber laser is critical for cold-atom experiments. With a narrow linewidth and >10 W of stable, polarization-maintaining power, it drives magneto-optical traps, laser cooling and trapping, optical pumping, and state preparation and detection, and it also serves Rydberg and precision-measurement setups that demand excellent beam quality.
In the near-IR, the 783 nm fiber laser is well suited for neutral-atom quantum platforms using rubidium, cesium, and ytterbium. Its narrow-linewidth, low-noise output supports optical-lattice and dipole trapping of ultracold rubidium and ytterbium, as well as blue-detuned nanophotonic traps for cesium atoms near optical waveguides, enabling precise atomic confinement, coherent manipulation, and atom–photon interfaces for quantum computing and quantum networking.
The 795 nm fiber laser addresses the rubidium D1 transition for gray-molasses cooling and clean optical pumping. Its 4 W of low-noise, single-frequency output supports sub-Doppler laser cooling and trapping, atomic interferometry, and quantum-sensing platforms that need a stable D1 source alongside their D2 lasers.
The ultra-stable, narrow-linewidth output of the 1064 nm fiber laser (≤20 kHz) makes it well suited for optical trapping and cooling of neutral atoms or ions. In optical dipole traps, far-off-resonant lasers (such as 1064 nm for certain atomic species) create conservative potentials that confine atoms with minimal photon scattering, enabling long coherence times. The low relative intensity noise (<-140 dBc/Hz>10 kHz) and high beam quality (M²<1.05) ensure very stable trapping potentials, which is critical to suppress heating and decoherence. Moreover, the high power (up to 50 W) is useful for creating deep potentials and for multiplexed or large-volume traps in quantum gas or quantum computing setups.
The same laser can be employed for qubit control via Raman transitions, stimulated two-photon processes, or state-dependent forces. For example, in atomic qubit architectures (e.g. alkali or alkaline-earth atoms), two-photon Raman coupling often uses detuned laser fields to address ground-state hyperfine transitions. The narrow linewidth and good frequency stability of this fiber laser help suppress off-resonant scattering and phase noise, improving gate fidelity. The polarization-maintaining (PM) output is also beneficial where polarization control is critical for selection rules in state coupling.
Beyond simple trapping and control, the 1064 nm fiber laser can support protocols for entangling qubits—either via mediated interactions or via motional coupling. High-power, low-noise beams can generate optical potentials that bring qubits into strong interactions (e.g. via controlled collisions, Rydberg-state interactions, or motional gates). The laser’s stability in amplitude, polarization, and pointing reduces decoherence channels during entangling operations.
Additionally, as quantum computing systems scale, multiplexed beam delivery becomes important (e.g. many traps addressed in parallel, optical lattices, cross-beam interrogation). A fiber-based design with polarization-maintaining architecture simplifies beam routing, splitting, and delivery to multiple zones or optical setups. It also reduces susceptibility to environmental drifts or mode distortions. In sum, a high-performance 1064 nm fiber laser can serve as a backbone resource in quantum computing platforms, enabling stable trapping, coherent control, and high-fidelity entangling operations.
Quantum networks rely on exquisitely controlled, low-noise optical signals to transmit quantum states (e.g. single photons, entangled photons) over fibers or free-space links. The 619 nm fiber laser from QTekLaser™ offers a compelling light-source solution for quantum networking platforms that exploit visible-wavelength transitions (for instance, in certain quantum memories, frequency converters, or quantum repeaters).
