M-FEMTO PR150 Amplified Mode-Locked Femtosecond Oscillator Laser at 1035 nm

Overview

The M-FEMTO PR150 is an industrial-grade amplified mode-locked femtosecond oscillator laser system engineered for ultrafast photonics research and precision applications requiring high temporal coherence, exceptional pulse-to-pulse stability, and robust long-term operation. Operating at a central wavelength of 1035 nm, the system leverages a diode-pumped Yb-doped fiber oscillator combined with a chirped-pulse amplification (CPA) architecture to deliver sub-150-fs pulses at repetition rates up to 100 MHz, with average output power exceeding 100 W. Its design adheres to fundamental principles of passive mode-locking via nonlinear polarization evolution (NPE) or semiconductor saturable absorber mirror (SESAM) stabilization—ensuring intrinsic timing jitter below 100 fs (integrated from 1 kHz to 10 MHz) and carrier-envelope phase (CEP) stability suitable for frequency comb metrology and attosecond science. The laser is optimized for integration into vacuum-compatible ultrafast beamlines, multiphoton microscopy platforms, and high-harmonic generation (HHG) setups where low-amplitude noise (<0.3% RMS, 10 Hz–1 MHz), thermal drift <50 pm/°C, and mechanical vibration immunity are critical.

Key Features

• Pulse duration: <150 fs (transform-limited, sech² profile, measured via autocorrelation)
• Repetition rate: 100 MHz (fundamental); optionally configurable via harmonic extraction or cavity dumping
• Average output power: ≥100 W, with power stability better than ±0.5% over 8 hours (23 °C ± 1 °C ambient)
• Beam quality: M² < 1.1, TEM₀₀ spatial mode, ellipticity <5%, divergence <0.3 mrad (full angle)
• Integrated dispersion management: Pre-chirp compensation via prism pair or grating compressor; group delay dispersion (GDD) tunable from −5000 to +5000 fs²
• Control interface: Ethernet (TCP/IP) and USB 2.0 with SCPI-compliant command set; remote monitoring of pump diode current, cavity temperature, and output power
• Environmental robustness: Operates continuously at ambient temperatures from 15 °C to 30 °C; relative humidity 20–70% non-condensing; compliant with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions)

Sample Compatibility & Compliance

The M-FEMTO PR150 is designed for use with standard optical components rated for high-peak-power ultrafast pulses, including dielectric mirrors (R > 99.9% @ 1030–1040 nm), fused silica and CaF₂ transmissive optics, and vacuum-compatible beam delivery systems. It meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. The system conforms to laser safety Class 4 per IEC 60825-1:2014, with integrated interlock circuitry (IEC 61508 SIL2 compliant) and key-controlled enable/disable functionality. For regulated environments, it supports audit-ready operation under GLP and ISO/IEC 17025 frameworks when paired with traceable calibration records and version-controlled firmware logs.

Software & Data Management

The laser ships with proprietary LabView-based control software (v4.2+) supporting real-time parameter logging, pulse characterization export (ASCII, HDF5), and automated alignment routines. All operational parameters—including pump current, cavity length feedback voltage, output power, and internal photodiode readings—are timestamped and stored locally with optional network-attached storage (NAS) synchronization. Data integrity is ensured through SHA-256 hashing of log files and optional 21 CFR Part 11 compliance modules (electronic signatures, role-based access control, and immutable audit trails). Firmware updates are delivered via signed binary packages validated against manufacturer public keys.

Applications

• High-harmonic generation (HHG) in gas-phase targets for extreme ultraviolet (EUV) coherent sources
• Pump-probe spectroscopy of carrier dynamics in 2D materials and perovskite semiconductors
• Time-resolved photoelectron spectroscopy (TR-PES) with sub-100-fs temporal resolution
• Multi-photon excitation in deep-tissue fluorescence lifetime imaging (FLIM) and optogenetics
• Ultrafast electron diffraction (UED) and MeV ultrafast electron microscopy (UEM) drive lasers
• Frequency comb stabilization for optical atomic clocks and precision spectroscopy (e.g., methane line referencing)

FAQ

What is the typical pulse energy and peak power?
At 100 MHz repetition rate and 100 W average power, pulse energy is ~1 µJ; with <150-fs duration, peak power exceeds 6.5 MW.
Is CEP stabilization available as an option?
Yes—fCEO detection and active feedback loop (using AOM or piezo-driven cavity mirror) can be integrated upon request, enabling octave-spanning combs.
Can the system be synchronized to external RF references?
Yes—the oscillator includes a low-jitter photodetector output and phase-locked loop (PLL) input for synchronization to external 10 MHz or 100 MHz references with sub-100-as RMS jitter.
What maintenance is required during normal operation?
No routine optical alignment is needed; periodic verification of cooling water flow rate (≥3 L/min) and temperature stability (±0.1 °C) is recommended every 6 months.
Does the system support vacuum integration?
Yes—vacuum-compatible versions (with CF-63 flange-mounted output port and bake-out rated to 80 °C) are available under custom configuration code VAC-PR150.
