Laserista

Laserista is a term used in Spanish-speaking contexts to refer to a person who works with lasers or uses lasers, either professionally or as a hobby. The word is formed from láser, borrowed from English acronym LASER, with the -ista suffix denoting a person associated with a field or activity.

Laseristas may be technicians, engineers, researchers, technicians operating laser equipment in manufacturing (cutting, welding, marking), medicine (laser surgery, dermatology), or scientific labs (spectroscopy, metrology, lidar). In industry, common laser types include CO2, Nd:YAG, fiber, and diode lasers. They may perform alignment, calibration, safety assessments, maintenance, and process optimization. In professional settings, training often covers optics fundamentals, electrical safety, laser safety standards (e.g., ANSI Z136 in the United States, IEC 60825 internationally).

Safety is a key concern; laseristas must manage beam hazards, reflections, eye and skin protection, and controlled access zones. There are certifications and roles such as laser safety officer and laser technician. The term can also informally describe hobbyists who build or operate laser show equipment, DIY laser cutters, or laser pointers, though this usage is less formal.

Within science and industry, laseristas contribute to material processing, medical technology, and research by enabling precise, controlled energy delivery. The field intersects with photonics and optoelectronics, and advances in fiber and solid-state lasers continue to expand practical applications.
