Fiber lasers are an essential tool in quantum computing. They play a significant role by providing precise and stable laser light required for various quantum operations and technologies. For example, laser cooling of atoms often requires high power sources with very specific frequencies matching atomic transitions to create atomic clouds of supercooled matter. 

In quantum computing, qubits can be represented by various physical systems, including trapped ions, superconducting circuits, or photons. For systems like trapped ions and atoms, precise control of qubits often requires laser beams to induce transitions between energy levels. 

Fiber lasers, known for their high stability and narrow linewidth, are ideal for these tasks. They can generate coherent light at specific wavelengths needed to interact with the qubits, enabling operations like qubit initialization and manipulation.

Our line of single-frequency fiber lasers and amplifiers exhibit extremely low noise and highly stable operation. We offer them at various wavelengths between 460 nm and 1950 nm, and at output powers of up to 10 W! With a narrow linewidth.
