Overview
The Avesta TiF-100 Series is a high-performance, solid-state, mode-locked titanium-doped sapphire (Ti:Sapphire) femtosecond oscillator engineered for precision ultrafast science applications. Operating on the principle of Kerr-lens mode-locking (KLM), the TiF-100 delivers transform-limited pulses with sub-100 fs duration across a broad spectral range—from 715 nm to 980 nm—enabling flexible excitation and probing in time-resolved spectroscopy, multiphoton microscopy, and attosecond pulse generation. Designed for stability and long-term reproducibility, the system integrates a robust monolithic cavity architecture with thermally compensated optics and vibration-damped mechanical housing. It is optimized for use with low-noise, continuous-wave diode-pumped solid-state (DPSS) pump lasers at 532 nm, supporting both integrated 10 W pump modules and external pump source integration—a configuration that facilitates compliance with lab-specific infrastructure constraints and budgetary requirements.
Key Features
- Wide tunability (715–980 nm) via intracavity birefringent filter and prism pair adjustment, enabling precise wavelength selection without external compressors or OPA stages
- Stable <100 fs pulse duration (FWHM, autocorrelation-measured) with excellent pulse-to-pulse amplitude stability (<0.5% RMS over 8 hours)
- High average power output: up to 1.55 W at 800 nm and 150 mW at 980 nm under 10 W 532 nm pump illumination
- Fixed 80 MHz repetition rate with low timing jitter (<30 fs RMS, integrated from 10 kHz to 10 MHz)
- Modular pump interface: supports either factory-integrated low-noise DPSS pump laser or customer-provided 532 nm pump source (up to 10 W, M² < 1.1)
- Hermetically sealed, alignment-free cavity design with automated thermal stabilization (±0.02 °C control)
- CE-marked and RoHS-compliant; designed to meet IEC 60825-1:2014 Class 4 laser safety requirements
Sample Compatibility & Compliance
The TiF-100 is compatible with standard optical table mounting (M6 threaded holes), fiber-coupled output options (optional), and integration into vacuum-compatible ultrafast beamlines. Its output beam exhibits TEM₀₀ spatial profile (M² < 1.05), suitable for coupling into single-mode fibers, nonlinear crystals (e.g., BBO, LBO), and scanning microscope objectives. The system complies with international laser safety standards (IEC 60825-1), electromagnetic compatibility directives (EN 61326-1), and environmental regulations (RoHS, REACH). While not certified for GMP or FDA 21 CFR Part 11 out-of-the-box, its deterministic optical performance and stable parameter logging (via optional software interface) support validation workflows required in GLP-compliant research environments—including ultrafast photochemistry, semiconductor carrier dynamics, and biomedical imaging studies.
Software & Data Management
The TiF-100 includes a USB 2.0–enabled control interface compatible with Windows-based host PCs. Avesta’s proprietary TiF-Control Suite provides real-time monitoring of cavity alignment status, pump power feedback, temperature setpoints, and emission wavelength tracking. All operational parameters—including wavelength setting, pump power level, and cavity dispersion compensation—are logged with timestamped metadata in CSV format, enabling traceability for audit-ready documentation. Optional LabVIEW™ and Python API libraries allow integration into custom automation frameworks, including those aligned with ISO/IEC 17025 calibration management protocols. No cloud connectivity or remote firmware updates are implemented—ensuring data sovereignty and network isolation for secure laboratory deployment.
Applications
- Time-resolved pump-probe spectroscopy (transient absorption, fluorescence upconversion)
- Multiphoton excitation microscopy (MPM) and second-harmonic generation (SHG) imaging
- Optical parametric amplifier (OPA) seeding for broadband IR/THz generation
- Attosecond science (high-harmonic generation in noble gases)
- Ultrafast electron diffraction (UED) and X-ray free-electron laser (XFEL) synchronization
- Nonlinear optical characterization of 2D materials and perovskite thin films
- Frequency comb stabilization and metrology-grade optical clock development
FAQ
Is the TiF-100 compatible with third-party pump lasers?
Yes—the system features a standardized 532 nm pump input port with adjustable focusing optics, supporting external DPSS lasers up to 10 W with M² < 1.1 and beam diameter between 1.5–2.5 mm.
What is the typical warm-up time to achieve spectral and power stability?
Full thermal equilibrium is achieved within 45 minutes of cold start; wavelength drift remains below ±0.2 nm and power fluctuation below ±0.3% over subsequent 12-hour operation.
Does the laser include dispersion compensation for pulse compression downstream?
The TiF-100 delivers near-transform-limited pulses directly from the oscillator; however, it includes provision for insertion of prism or grating-based compressors in the output path for fine-tuning group delay dispersion (GDD) in amplified systems.
Can the repetition rate be adjusted?
No—the TiF-100 operates at a fixed 80 MHz repetition rate determined by cavity length; variable-repetition-rate variants (e.g., harmonic mode-locking configurations) are available as custom-engineered models upon request.
Is remote diagnostics or service support available?
Avesta offers remote-assisted alignment guidance and firmware-level diagnostics via encrypted VNC session; hardware service requires on-site technician dispatch or return-to-factory repair under warranty terms.
