AOSense, a developer of atom-optic sensors, precision laser systems, and quantum technologies, offers a range of tapered amplifiers designed to generate coherent high-power laser beams while preserving the characteristics of the seed laser source. The company provides both fiber-pigtailed and free-space tapered amplifier configurations to support demanding applications in quantum science, precision measurement, and advanced photonics.

Tapered amplifiers are widely used when applications require significantly higher optical power than can be obtained directly from a seed laser. According to AOSense, the amplifiers produce a coherent high-power output beam that inherits the wavelength, linewidth, and spectral properties of the input laser, enabling power scaling without compromising the performance of the original source.

The company’s tapered amplifier portfolio includes compact free-space and fiber-pigtailed units. The fiber-pigtailed version incorporates a fiber-coupled input, simplifying integration with existing laser architectures and optical systems. Both configurations are designed to provide high optical power while maintaining excellent beam quality for precision applications.

AOSense offers tapered amplifier models operating around 780 nm and 852 nm, with output powers exceeding 3 W. The devices feature beam quality values below M² = 1.7, amplified spontaneous emission (ASE) suppression greater than 40 dB, and polarization extinction ratios of approximately 100:1, supporting applications that require stable and spectrally clean laser output.

The amplifiers are engineered for use in a variety of quantum and atomic physics applications. AOSense identifies laser cooling and trapping, cold-atom sensors, electromagnetically induced transparency (EIT), and quantum spectroscopy among the key areas where high-power coherent laser sources are essential. By amplifying seed lasers while retaining their spectral characteristics, the devices help researchers achieve the optical power levels required for advanced experimental setups.

Beyond research laboratories, the tapered amplifiers are also suitable for integration into commercial laser platforms. The company notes their use in master oscillator power amplifier (MOPA) systems and external cavity laser architectures, where optical power scaling is required without sacrificing coherence or spectral purity. The compact design of the amplifier modules enables straightforward incorporation into space-constrained optical systems. According to AOSense, both free-space-input and fiber-input options are available, while custom wavelength configurations can also be supported for specialized applications. The company additionally offers versions with output powers of 1 W, 2 W, and 3 W, providing flexibility for different performance requirements.

As quantum technologies, atomic sensors, and precision photonics systems continue to evolve, the demand for stable, high-power laser sources remains a critical requirement. With its tapered amplifier portfolio, AOSense provides researchers, system developers, and laser manufacturers with scalable optical amplification solutions designed to support next-generation quantum and photonic applications.
