Modulaser

Modulaser is a modular laser system architecture designed to provide scalable power and wavelength flexibility by assembling multiple laser modules into a single platform. The concept centers on configuring a laser source from discrete units rather than a single monolithic device, enabling rapid customization and upgrades.

In a typical modulaser, individual diode- or fiber-based laser modules are configured in parallel or in a coherent combination scheme. The modules can be selected for different wavelengths, output powers, or beam qualities, enabling customization without replacing a single large unit. This modular approach supports incremental power scaling and parameter tuning to meet specific process or research requirements.

Beam combining can be incoherent (power summation with beam path alignment) or coherent (phase-locked combination allowing higher brightness). Coherent schemes require active phase control and precise optical alignment, while incoherent approaches emphasize robustness and lower sensitivity to phase errors. Control systems for modulasers often integrate thermal management, power balancing, fault monitoring, and safety interlocks.

Applications include materials processing (cutting, drilling, welding), micromachining, precision manufacturing, medical and cosmetic lasers, LiDAR and sensing, and research laboratories requiring rapid reconfiguration of laser parameters. The modular structure is well suited to prototyping and factory environments where product lines frequently evolve.

Advantages of modulasers include scalability, redundancy, and shorter procurement cycles, as well as easier maintenance and upgrades by swapping individual modules. Limitations involve increased system complexity, thermal management challenges, alignment sensitivity (especially for coherent combining), and higher control software requirements. The term is used to describe various modular laser architectures rather than a single standard, emphasizing interoperability and adaptability.
