Overview
The Rayscience C00109 is a high-power, continuous-wave (CW) multimode diode laser system engineered for industrial pumping, materials processing, and scientific excitation applications requiring stable, high-brightness optical output. Designed around a fiber-coupled architecture with a 400 µm core / 0.22 NA delivery fiber, the system delivers ≥350 W optical power directly at the fiber terminus under nominal operating conditions. Its emission spectrum is centered on industrially optimized wavelengths—805–810 nm, 915 nm, 940 nm, or 975–980 nm—with tight spectral control (FWHM <8 nm, down to <5 nm in narrow-band configurations) and low thermal wavelength drift (~0.3–0.4 nm/K), enabling compatibility with absorption-matched gain media such as Nd:YAG, Yb-doped fibers, and vanadate crystals. The laser head employs conduction-cooled semiconductor stacks integrated with precision thermoelectric stabilization, operating within a controlled ambient range (+15 to +30 °C) and requiring external chiller support (≥1000 W cooling capacity, 4 bar water pressure, 20 °C inlet temperature). All electrical and optical interfaces comply with IEC 60825-1:2014 Class 4 laser safety requirements, and the system bears CE marking and RoHS 2002/95/EC certification.
Key Features
- Fiber-coupled output delivering ≥350 W CW power at the fiber end with high spatial stability and beam parameter product (BPP) suitable for end-pumping and side-pumping architectures
- Multiple center wavelength options (805–810 nm, 915 nm, 940 nm, 975–980 nm) selectable at time of order to match specific absorption peaks of solid-state or fiber gain media
- Low spectral width (<8 nm FWHM; <5 nm optional) and minimal thermal wavelength drift ensure consistent pump absorption efficiency across thermal transients
- Integrated pilot beam (625 ±5 nm, >1 mW) for rapid optical alignment and path verification without interrupting main laser operation
- Real-time analog monitor diode (0–2 V output, 5 VDC bias) providing proportional feedback for closed-loop power regulation and process logging
- Robust mechanical design: compact laser head (71 × 33 × 34 mm, 6.2 kg), IP52-rated housing, and LD80 fiber connector interface compatible with industry-standard collimation and focusing optics
- Rated MTBF of 20,000 hours under recommended operating conditions (BOL current ≤53 A, junction temperature maintained ≤45 °C)
Sample Compatibility & Compliance
The C00109 is intended for integration into OEM laser systems, scientific pumping platforms, and industrial thermal processing stations—not for direct sample irradiation. Its 400 µm / 0.22 NA fiber output enables efficient coupling into rod-, slab-, or fiber-based gain modules used in DPSS lasers, MOPA amplifiers, and direct-diode material treatment systems. The device complies with EU Directive 2002/95/EC (RoHS2) and carries CE marking per EN 60825-1:2014 (Class 4 laser product). It meets essential requirements of the EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU. While not supplied with FDA 21 CFR Part 11-compliant firmware by default, the analog monitor diode output and TTL-compatible enable/disable signals support integration into GLP/GMP-auditable control environments when paired with validated data acquisition hardware.
Software & Data Management
The C00109 operates as a hardware-level subsystem with no embedded microcontroller or proprietary software stack. Control is implemented via analog and digital I/O: modulation input (TTL or 0–5 V), interlock loop (dry contact), and monitor diode output (0–2 V linear with output power). Users integrate the laser into existing PLC, DAQ, or motion-control platforms (e.g., National Instruments LabVIEW, Beckhoff TwinCAT, or custom C/C++ applications) for synchronized power ramping, fault logging, and thermal profiling. Raw monitor diode voltage data—when sampled at ≥1 kHz—enables real-time power stability assessment (±2% typical linearity) and long-term degradation trending. For traceable calibration, Rayscience provides factory-measured L-I-V curves and spectral characterization reports (ISO/IEC 17025-accredited test lab documentation available upon request).
Applications
- High-power diode pumping of Nd:YAG, Nd:YVO₄, and Yb:YAG solid-state lasers in scientific and medical OEM systems
- Primary pump source for Yb-doped fiber amplifiers and ultrafast chirped-pulse amplifier (CPA) front-ends
- Industrial direct-diode heating, cladding, and brazing where high radiant flux and uniform intensity distribution are required
- Accelerator-driven light sources and free-electron laser (FEL) photocathode drive systems requiring high-repetition, stable CW excitation
- Calibration reference source for radiometric and photometric transfer standards in metrology laboratories
FAQ
What is the maximum allowable case temperature during continuous operation?
The laser head must be maintained between +15 °C and +30 °C ambient. Exceeding +30 °C may trigger thermal shutdown or accelerate degradation; active liquid cooling with stable 20 °C inlet temperature is mandatory.
Is the fiber connector included with the laser head?
No—the LD80 receptacle is integrated into the laser head housing, but the mating LD80 fiber connector and termination are supplied separately per customer-specified fiber length and jacketing.
Can the C00109 be modulated at frequencies above 10 kHz?
Yes—via the analog modulation input (0–5 V, bandwidth ≥100 kHz) or TTL enable/disable (rise/fall time <1 µs); however, power stability at high-frequency modulation depends on external driver design and thermal mass management.
Does Rayscience provide spectral measurement reports for individual units?
Yes—each unit ships with a test certificate including measured center wavelength, FWHM, and L-I-V characteristics; full spectral scans (0.1 nm resolution) and thermal drift coefficients are available as optional add-ons.
What is the definition of BOL and EOL in the electrical specifications?
BOL = Beginning of Life (initial 100 hours, rated at 53 A operating current); EOL = End of Life (defined as 20,000-hour operational lifetime or 20% power drop from BOL, whichever occurs first; max allowed current increases to 72 A to maintain nominal output).
