Focusing Lens/Collimating Lens
Fiber laser focusing lenses: made from fused silica with antireflection coatings on both sides, they focus beams to high-energy-density spots for processing workpieces. Applications include laser cutting, welding, cladding, and hardening. Spherical focusing lenses: a two-element spherical lens combination is generally recommended to minimize spherical aberration. Aspheric focusing lenses: aspheres introduce no spherical aberration into the transmitted wavefront and achieve diffraction-limited performance, allowing one aspheric lens to replace a conventional multielement spherical combination. Fiber laser collimators: compress the divergence angle of a divergent laser beam for parallel propagation. Lens design and application resemble focusing lenses; singlet, multielement, or aspheric versions can be selected. Aspheres provide the best results, followed by multielement combinations.

A microlens array (MLA) is a high-precision optical component composed of hundreds or thousands of tiny, uniformly arranged micro lenses on a single flat substrate. Unlike traditional single lenses that focus one light beam, a microlens array can split, homogenize, and reshape light on a micro scale. It is widely paired with VCSELs, lasers, and image sensors, becoming a core part of modern miniature optical systems.
A laser bar is an array semiconductor laser chip integrated with dozens of emitters, which realizes hundred-watt quasi-continuous output on a single chip. With regular emitter arrangement and controllable fill factor, integrated thermal design and superior wall-plug efficiency compared to single chips, it acts as the core light source for high-power pumping, medical lasers and precision processing.
