Industrial Applications

From 3D Nanoprinting to Terahertz Inspection and Optical Metrology to LIDAR, Calmar Lasers are enabling the Industrial World

Lasers have become ubiquitous tools in the manufacturing environment, providing higher productivity, improved quality, reduced cost and increased efficiency in many of today’s industrial processes.  Advances in fiber laser technology over the past 20 years have accelerated their adoption and broadened the application space, from low power marking to high power kilowatt class systems for cutting and welding.  With their unique performance characteristics, Calmar ultrafast fiber lasers have found widespread use in this sector for metrology, quality control, fine structure materials processing and other areas. 

Recently, terahertz time-domain spectroscopy (THz-TDS) has seen significant growth, as a non-destructive technique for determining the thickness of industrial coatings and films in a wide range of materials.  From measuring electrode coatings in EV battery manufacturing to automotive paints to multi-layers coatings in pharmaceuticals, THz systems are enhancing product performance and facilitating process and quality control.  Calmar’s ultrafast fiber lasers have been at the heart of these THz tools for over 20 years.  The Mendocino series of benchtop and OEM modules, with different wavelength and fiber delivery options, are the perfect sources for the generation of terahertz radiation from either GaAs or InGaAs photoconductive switches.

Lasers are playing a key role in driving Industry 4.0, especially the rise of additive manufacturing.  The high peak power of ultrafast laser pulses enables two-photon absorption in photopolymers and the realization of 3D nanoprinting, yielding complex structures with incredibly fine feature sizes.  With its compact footprint and high power, the Carmel X-series facilitates desk top 3D nanoprinting platforms with high throughput and sub-micron resolution.

Eye-safe 3D sensing and LIDAR are gaining significant popularity for mapping objects and environments in industrial automation, automotive, robotics and other industries.  Calmar has kept pace with these developments by innovating its Mendocino product line with application-specific 1550 nm sources. The Mendocino LDR module is a battery-powered source with picosecond pulse widths and MHz repetition rates, ideal for high-resolution scanning in remote locations.

Whether it be a robust, low power, laser source such as the Mendocino or a higher power laser, such as the Carmel or Cazadero, Calmar offers an ultrafast fiber laser solution for your industrial applications.
