compact design
fiber-coupled option
high power output
multiple wavelengths offered
The AOSense tapered amplifier (TA) provides a coherent high-power beam, inheriting all properties from the seed source. TA’s are an essential optical component for quantum sciences, such as laser cooling and trapping, cold atom sensors, electromagnetically induced transparency, and quantum spectroscopy. The TA is also used in commercial laser modules, including master oscillator power amplifier (MOPA) lasers and external cavity lasers.
AOSense offers two compact TA units: free-space tapered amplifier unit and fiber pigtailed tampered amplifier unit, which has fiber coupled input.
