TrueMode™ Fiber Laser Cavities
OFS has been developing and manufacturing high power components and modules since the early years of fiber lasers. Today, we continue to introduce new products in this area. OFS’ proprietary technologies in the areas of optical fibers and components are integrated in our TrueMode fiber laser cavity and TrueM2™ Beam Combiner platforms. These platforms enable machine manufacturers to build their own fiber laser source using worry-free modular architecture, enabling them to produce a customized fiber laser based on their specific requirements and target market.
OFS TrueMode fiber laser cavities provide a complete platform with matching components and modules that enable delivery of true single-mode output at kilowatt power levels. The customer is able to select pump diode modules of their choice (commercially available or in house design). The true single-mode design, and its near ideal splice loss capability, provides our customers an optical engine with consistent high optical-to-optical efficiency and beam quality.
OFS TrueMode cavities are now categorized into two platforms: TrueMode-SP and TrueMode-kW. The TrueMode-SP is designed for use in 500W applications. Providing 8 pump ports, the TrueMode-SP is designed for use with diodes delivering greater than 100W of pump power.
The TrueMode-kW is designed for kilowatt applications and, when used with our TrueM2 beam combiners, multi-kilowatt applications. The breakthrough design of the TrueMode-kW platform uses large numerical aperture pump modules and incorporates a large pump module count. With up to 36 pump ports, the TrueMode-kW cavity can be used with diodes delivering greater than 50W of pump power.
