Overview
The INO LaserNGN Tapered-Fiber-Based High-Power Ultrafast Fiber Amplifier is a purpose-engineered OEM-grade optical amplification module designed for demanding scientific and industrial ultrafast laser systems. Leveraging a custom-designed ytterbium-doped tapered polarization-maintaining photonic crystal fiber (Yb-MCOF-35/250-56/400-07-2.2-PM) as its gain medium, this amplifier operates on the principle of stimulated emission in a single-mode, large-mode-area (LMA) waveguide architecture. The tapered geometry enables efficient pump absorption while simultaneously suppressing higher-order mode excitation and nonlinear effects—critical for maintaining beam quality and pulse fidelity at multi-hundred-watt average power levels. Optimized for operation at 1030 nm and 1064 nm, the LaserNGN module delivers up to 100 W average output power with >70% optical-to-optical conversion efficiency and a small-signal gain exceeding 30 dB. Its near-Gaussian, linearly polarized output supports seamless integration into master oscillator power amplifier (MOPA) architectures, chirped pulse amplification (CPA) systems, and frequency conversion stages requiring high peak power (>500 kW) and low temporal distortion.
Key Features
- High-power OEM module engineered for integration into ultrafast laser platforms
- Tapered Yb-doped PM photonic crystal fiber gain medium enabling scalable average power with preserved beam quality (M² < 1.2 typical)
- High nonlinear threshold due to enlarged effective mode area and optimized dispersion management
- Linearly polarized, near-Gaussian output with excellent pointing stability (< 5 µrad RMS over 8 hours)
- Compact, air-cooled mechanical design compatible with standard 19″ rack-mount or benchtop integration
- Robust architecture with integrated thermal monitoring, pump diode current regulation, and interlock-ready safety interface (IEC 60825-1 compliant)
Sample Compatibility & Compliance
The LaserNGN amplifier is compatible with picosecond seed sources operating at repetition rates from 100 kHz to 10 MHz and pulse durations ranging from 500 fs to 20 ps. It accepts free-space collimated input beams (1/e² diameter: 1.2–2.0 mm) or fiber-pigtailed inputs (FC/APC, PM980) via optional adapters. The module conforms to IEC 60825-1:2014 (Class 4 laser product), RoHS 2015/863/EU, and CE marking requirements. All firmware and control logic are designed to support GLP-compliant lab environments; full audit trail logging (including pump current, temperature, and output power history) is available upon request for ISO/IEC 17025 or FDA 21 CFR Part 11-aligned workflows.
Software & Data Management
The LaserNGN module includes a USB-C and RS-232 interface supporting ASCII-based SCPI command set for remote parameter control (e.g., pump current ramping, interlock enable/disable, status polling). Optional LabVIEW™, Python (PyVISA), and MATLAB® drivers are provided for automated system integration. Real-time telemetry—including diode junction temperature, thermistor readings, photodiode-monitored output power, and fault flags—is timestamped and exportable in CSV or HDF5 format. Firmware updates are performed via signed binary packages to ensure traceability and integrity per IEC 62443-3-3 security guidelines.
Applications
- High-energy picosecond MOPA systems for precision micromachining of transparent dielectrics and metals
- Primary amplification stage in CPA-based Ti:sapphire or Yb-fiber front-ends targeting few-cycle pulse generation
- Pump source for optical parametric amplifiers (OPAs) and difference frequency generation (DFG) in mid-IR spectroscopy
- Seed amplification in industrial-grade ultrafast oscillators used for LIBS, time-resolved fluorescence, and pump-probe experiments
- Frequency doubling and tripling setups requiring high peak power, polarization purity, and spatial coherence
- Development platform for next-generation coherent beam combining and spectral beam combining architectures
FAQ
What seed laser specifications are recommended for optimal performance?
A linearly polarized, diffraction-limited picosecond oscillator with average power between 10–500 mW, repetition rate ≥500 kHz, and pulse duration ≤20 ps is ideal. Input polarization extinction ratio should exceed 20 dB.
Can the LaserNGN be operated in CW mode?
Yes—the module supports both pulsed and CW operation; however, saturation energy and gain dynamics are specified under pulsed conditions. CW output is limited to ≤80 W to maintain thermal stability.
Is custom wavelength tuning supported?
The standard configuration is fixed at 1030 nm or 1064 nm. Custom center wavelengths between 1020–1080 nm are available as engineering options subject to gain fiber redesign and extended lead time.
Does the module include built-in diagnostics for long-term reliability monitoring?
Yes—integrated thermistors, monitor photodiodes, and EEPROM-stored calibration coefficients enable predictive maintenance and drift compensation across 10,000+ operational hours.
What is the warranty and service support structure?
INO provides a 24-month limited warranty covering materials and workmanship. Extended calibration and preventive maintenance contracts are available through authorized service centers in Europe, North America, and APAC regions.
