New Focus, a Newport Corporation brand, has introduced a series of semiconductor tapered amplifiers for high-power tuneable and fixed-wavelength applications.

The Vamp series is designed to accept many fibre-coupled seed sources, providing simple alignment and helping protect the chip from unintentional misalignment.

The design includes output isolation, over-current protection and input seed monitoring in every amplifier to ensure stable operation.

These features also protect the chip from self lasing and other hazardous operating conditions.

The new tapered amplifier series produces more than 1W of tuneable signal frequency radiation when seeded with an appropriate source, such as New Focus’s Vortex II and Velocity precision tuneable lasers.

The Vamp can also operate with many homemade seed sources, making it suitable for quality measurements in the laboratory.

The New Focus engineering team has implemented a power-locking loop that reduces the amplitude noise and drift.

The power output remains stable and quiet over the entire operating temperature range, which results in higher-quality data in shorter amounts of time, according to the company.

The Vamp offers high ASE rejection to improve the signal-to-noise ratio, making it suitable for atomic cooling and spectroscopy and for creating Bose-Einstein condensates.
