A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term laser is an acronym for light amplification by stimulated emission of radiation. Laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low-divergence beam, or can be converted into one with the help of optical components such as lenses. Typically, lasers are thought of as emitting light with a narrow wavelength spectrum ("monochromatic" light). This is not true of all lasers, however: some emit light with a broad spectrum, while others emit light at multiple distinct wavelengths simultaneously. The coherence of typical laser emission is distinctive. Most other light sources emit incoherent light, which has a phase that varies randomly with time and position.

Quantum information is fragile and often difficult to protect during experiments. Protecting qubits from accidental measurements is essential for controlled quantum operations, especially during state-destroying measurements ...

Flexible Optical produces high-quality replicated microlens arrays specially for the use with FrontSurfer wavefront sensors. As a standard option, we offer a hexagonal array of 127 microlenses with a focal distance of 18 mm and a pitch of 300 µm, mounted in a C-mount.Besides, Flexible Optical offers a range of microlens arrays fabricated in glass and fused silica with small numerical aperture and 99% optical fill factor. Microstructures provide for optimum spectral efficiency (UV to far infrared) and for the best mechanical and thermal stability. These arrays work with very high optical loads. To provide a cost-efficient solution, all listed arrays can be replicated in series in plastic. Microlens arrays with orthogonal or hexagonal arrangements are available.
