Designed for demanding industrial, scientific, and illumination applications, these arrays deliver exceptional peak power, thermal robustness, and integration flexibility in compact, rugged packages.
Product Overview
Frankfurt Laser Company’s new diode laser array families are engineered to perform under elevated thermal loads while maintaining superior optical and electrical characteristics. They are especially suitable for:
-
Pumping Sources
-
Laser Processing
-
Scientific Research
-
Illumination
Each series targets different use cases and form factors while sharing a common commitment to high reliability, multi-wavelength capability, and efficient thermal management.
Key Series & Features
FK Series – High-Power, Multi-Wavelength Conduction-Cooled Diode Laser Array
The FK Series is a compact, conduction-cooled array optimized for operation at elevated temperatures with per-bar output power from 100 W to 200 W. It supports flexible configurations including different wavelengths, bar counts, pitches, and optional single-wavelength outputs.
Highlights:
-
High peak power (100–200 W per bar)
-
Multi-wavelength integration
-
AuSn solder packaging for robust thermal/electrical contact
-
Designed for high-temperature operation
-
Customizable: number of bars (1–15), bar pitch, wavelengths, and bar length
FF Series – Wide-Temperature, Dual-Wavelength Conduction-Cooled Arrays
The FF Series extends operation across wide temperature ranges with dual-wavelength stacking capability. It combines high peak power and reliability in a conduction-cooled format ideal for systems requiring stable multi-stack laser illumination or pumping.
Highlights:
-
Dual wavelength integration
-
High peak power with stable optical output
-
Wide-temperature tolerance
-
Stack configurations (varying numbers of stacks and bars)
-
Customizable stack-to-stack pitch and emission area
FA Series – Polygonal, High-Peak-Power Conduction-Cooled Arrays
The FA Series uses hexagonally arranged stacks (6–18) with 1–4 bars per stack, targeting high-temperature environments while delivering high peak power per bar (100 W / 200 W). The polygonal architecture enables scalable power in a compact footprint.
Highlights:
-
Hexagonal multi-stack arrangement for scalable high power
-
Customizable bar counts and array pitch
-
Designed for sustained high-temperature operation
-
Flexible packaging options to meet system-level integration needs
