Innolume has achieved 950 mW of continuous wave fiber-coupled output power at 1130 nm with its new BOA1130040YY950MXXXX amplifier, the company says. This power level is useful for applications like thulium atomic spectroscopy, and is delivered with a drive current of 2.2 An at 25°C while processing a 100 mW input signal. The amplifier’s 40 nm 3-dB gain bandwidth supports experiments needing higher infrared power and potential frequency-conversion applications, extending Innolume’s portfolio to shorter wavelengths.

This amplifier uses a quantum-dot gain medium as an alternative to traditional InGaAs/GaAs quantum-well designs commonly used at this wavelength, offering a different approach to high-power operation. The device is housed within a compact 14-pin butterfly package and incorporates an integrated thermoelectric cooler for stable temperature control during operation. Higher power levels provide a greater optical budget for experiments and enable frequency conversion techniques, such as generating visible light through frequency doubling.
Innolume designed the BOA1130040YY950MXXXX to complement its existing high-power booster optical amplifiers operating at 1260 nm and 1310 nm, broadening the range of available wavelengths. Innolume states that “seed-laser selection must account for any optical losses before the amplifier,” highlighting the importance of system-level considerations for optimal performance. The BOA is available with PM980 or HI1060 fiber options, and a 900 µm loose tube is also offered, providing flexibility for integration into various optical systems.
