Montfort MF-1045-FS Series Femtosecond Laser System (100-fs Class, 1.5 W / 3 W Output)

Overview

The Montfort MF-1045-FS Series is a diode-pumped, Yb-doped solid-state femtosecond oscillator engineered for high stability, compact integration, and laboratory-to-field deployment in ultrafast photonics applications. Operating at a center wavelength of 1045 nm with pulse durations down to <100 fs (FWHM, sech² profile), this laser leverages semiconductor saturable absorber mirror (SESAM) passive mode locking to generate transform-limited pulses with exceptional temporal fidelity. Its all-solid-state architecture—free of liquid gain media or complex cavity alignment—ensures long-term reliability and low maintenance overhead. Designed for demanding environments, the system supports 24 V DC operation and exhibits robust thermal management, enabling continuous-duty performance without active water cooling. As a turnkey source for ultrafast science and industrial metrology, it delivers precise timing jitter (<100 fs RMS, integrated from 10 kHz to 10 MHz), narrow optical bandwidth (<10 nm), and intrinsic amplitude noise <0.3% RMS (10 Hz–10 MHz), meeting stringent requirements for pump-probe spectroscopy, nonlinear frequency conversion, and seeded amplification.

Key Features

• Fully integrated, self-contained oscillator: No external pump lasers or alignment-sensitive optics required
• Two power variants: 1.5 W and 3 W average output—optimized for seeding amplifier stages or direct application use
• SESAM-based passive mode locking ensures shot-to-shot pulse-to-pulse stability and low timing jitter
• Beam quality maintained at M² < 1.2 across full power range—enabling diffraction-limited focusing for precision ablation and THz generation
• Compact laser head options: 520 × 100 × 100 mm (high-power variant) or 309 × 140 × 80 mm (space-constrained integration)
• 24 V DC input compatibility enables battery or vehicle-mounted operation—validated for field-deployable LIBS and LIDAR systems
• Integrated thermal stabilization and vibration-damped mechanical design ensure operational consistency under ambient fluctuations

Sample Compatibility & Compliance

The MF-1045-FS is compatible with standard ultrafast optical components including chirped mirrors, grating compressors, OPA/OPO crystals (e.g., BBO, BiBO, KTA), and photoconductive THz emitters. Its 1045 nm fundamental output serves as an efficient pump for ytterbium-based optical parametric oscillators (OPOs) and Ti:sapphire amplifier seeds. The system complies with IEC 60825-1:2014 as a Class 4 laser product, incorporating interlock-ready connectors, key-switched emission control, and embedded beam shutter logic. All units are CE-marked and RoHS-compliant. For regulated environments—including GLP/GMP laboratories and FDA-regulated instrumentation development—the controller firmware supports optional audit trail logging and user-access level configuration (via RS232/USB), aligning with foundational principles of 21 CFR Part 11 for electronic records integrity.

Software & Data Management

Operation is managed via Montfort’s proprietary LaserControl GUI (Windows-based), offering real-time monitoring of output power, repetition rate drift, internal temperature gradients, and SESAM reflectivity diagnostics. The software provides programmable pulse picking (via external TTL trigger), adjustable repetition rate fine-tuning (±1 MHz), and automated warm-up calibration sequences. All operational parameters are exportable in CSV format with timestamped metadata. Remote control is supported through ASCII command protocol over USB virtual COM port or RS232, facilitating integration into LabVIEW, Python (PySerial), or MATLAB automation frameworks. Firmware updates are delivered via signed binary packages with SHA-256 verification—ensuring traceability and cybersecurity compliance in networked lab infrastructures.

Applications

• Pump source for picosecond OPOs and regenerative amplifiers requiring low-jitter, high-repetition-rate seed pulses
• Time-resolved spectroscopy (TRTS, TA, 2D-IR) where sub-100 fs temporal resolution is critical
• THz time-domain spectroscopy (THz-TDS) using photoconductive antennas or optical rectification in ZnTe/DAST
• Ultrafast micro-machining of transparent dielectrics (fused silica, sapphire) and thin-film patterning
• Laser-induced breakdown spectroscopy (LIBS) with improved plasma initiation reproducibility
• Particle image velocimetry (PIV) in high-speed fluid dynamics with dual-pulse capability
• Optical damage threshold testing per ISO 21254 standards for coatings and bulk materials
• Supercontinuum generation in photonic crystal fibers for broadband OCT and frequency comb stabilization

FAQ

What is the typical pulse energy for the 1.5 W and 3 W models at 75 MHz?
At 75 MHz repetition rate, the 1.5 W model delivers ~20 nJ/pulse; the 3 W model delivers ~40 nJ/pulse.
Can the laser be synchronized to an external clock signal?
Yes—both models support external synchronization via TTL input with adjustable phase delay (0–360°, 1 ps resolution) for pump-probe or multi-laser experiments.
Is vacuum or purged operation required for long-term stability?
No—sealed, convection-cooled design eliminates need for purge gas or vacuum enclosures; stable operation verified from 15–35 °C ambient.
Does the system include dispersion compensation optics?
No—compressor optics (e.g., chirped mirror pairs or prism/grating setups) are application-specific and sold separately.
What service and calibration options are available post-warranty?
Montfort offers biannual factory recalibration (traceable to PTB standards), on-site performance validation, and extended warranty packages up to 5 years.
