Onefive Origami-05 Femtosecond Laser System

Overview

The Onefive Origami-05 is a turnkey, industrial-grade femtosecond laser system engineered for ultra-low phase and amplitude noise, exceptional temporal stability, and robust environmental insensitivity. Based on mode-locked Yb-doped fiber oscillator architecture, it delivers transform-limited pulses in the 1025–1070 nm spectral window with pulse durations tunable from 90 to 400 fs. Its core design eliminates internal optical amplification stages—thereby suppressing amplified spontaneous emission (ASE) background—and achieves intrinsic spectral purity and temporal fidelity unattainable in amplified or cavity-dumped systems. The laser operates without water cooling, forced-air convection, or warm-up delays, maintaining stable output across ambient temperatures from 10 °C to 40 °C. This makes it uniquely suited for integration into field-deployable instrumentation, metrology platforms, and time-resolved spectroscopy setups where long-term drift, thermal hysteresis, or acoustic interference must be minimized.

Key Features

• Ultra-low intensity and phase noise: Industry-leading specifications enabled by all-fiber, non-amplified oscillator design—no ASE floor, no pulse pedestals, no spectral sidebands.
• Thermoelectric (Peltier) stabilization of both pump diode and gain fiber: Ensures wavelength and pulse width stability without external chillers or compressors.
• True plug-and-play operation: Single-button start-up; no software, no drivers, no configuration—ready for continuous 7×24 operation within seconds of power-on.
• Integrated optical isolator: Prevents back-reflection-induced instabilities in sensitive interferometric or nonlinear optical configurations.
• Hardware-based synchronization interface: Accepts external TTL or sine-wave reference clocks (10 MHz–1.3 GHz); automatic lock with <3 ps RMS timing jitter and zero interruption during re-locking.
• Compact, rack-mountable chassis (2U height): Designed for OEM integration and laboratory deployment with minimal footprint and acoustic emissions (<30 dB(A)).

Sample Compatibility & Compliance

The Origami-05 is compatible with standard free-space optical paths and optional polarization-maintaining (PM) fiber coupling (FC/APC or FC/PC). It meets international laser safety requirements per IEC 60825-1:2014 (Class 4), carries CE marking under the EU Machinery and EMC Directives, and complies with RoHS 2011/65/EU. Its deterministic pulse-to-pulse timing and absence of relaxation oscillations enable seamless use in applications governed by GLP/GMP workflows—including time-of-flight mass spectrometry, optical coherence tomography (OCT), and frequency comb referenced metrology—where traceability, audit readiness, and reproducibility are critical. While not FDA 21 CFR Part 11–certified out-of-the-box, its deterministic behavior and hardware-triggered synchronization support validation pathways for regulated environments.

Software & Data Management

The Origami-05 operates autonomously without host software. All control logic—including repetition rate tuning, output enable/disable, and sync acquisition—is implemented in FPGA-based firmware. Optional USB-C or RS-232 interfaces provide read-only status telemetry (temperature, pump current, lock status, pulse energy estimate) for logging and remote health monitoring. No proprietary drivers or runtime dependencies are required. For users requiring automated calibration or system-level orchestration, ASCII-command protocols are documented in the Engineering Interface Manual (EIM), supporting integration with LabVIEW, Python (PySerial), or MATLAB via standard serial abstraction layers. Audit trails may be generated externally using timestamped serial logs aligned to NTP-synchronized host clocks.

Applications

• Time-resolved photoluminescence and pump-probe spectroscopy requiring sub-100 fs resolution and shot-to-shot phase coherence.
• Fiber-optic distributed acoustic sensing (DAS) and phase-sensitive OTDR (φ-OTDR) for pipeline integrity monitoring and perimeter intrusion detection.
• Frequency comb seeding for mid-IR generation via difference-frequency mixing in orientation-patterned GaAs or PPLN waveguides.
• Multi-photon microscopy excitation sources where low thermal load and diffraction-limited beam quality (M² < 1.1) maximize signal-to-background ratio.
• Optical clock distribution and RF photonics, leveraging its sub-3 ps jitter and compatibility with 10 MHz–1.3 GHz reference standards.
• Terahertz time-domain spectroscopy (THz-TDS) pump sources with high dynamic range due to absence of residual ASE and clean pulse contrast.

FAQ

Is the Origami-05 suitable for vacuum or cleanroom environments?
Yes—the unit contains no outgassing elastomers or lubricants; all housings are anodized aluminum or stainless steel, and the thermoelectric cooler uses hermetically sealed modules compliant with ISO 14644-1 Class 5 airflow requirements.
Can pulse duration be adjusted in real time during operation?
No—pulse width is factory-set per model variant (e.g., Origami-05 defaults to ~250 fs); fine-tuning requires optional dispersion compensation modules installed externally.
Does the laser support burst-mode operation?
Not natively; it delivers continuous train output at fixed repetition rates. Burst modes require external electro-optic modulation synchronized to the internal clock.
What is the typical warm-up time to full specification stability?
Less than 60 seconds from cold start; full thermal equilibrium (for maximum long-term wavelength stability) is achieved within 15 minutes.
Is PM fiber output available as a standard option?
Yes—PM980 or PM1550 fiber pigtailing (FC/APC connector) is offered as a configurable option at time of order, with extinction ratio >20 dB and alignment verified per IEC 61300-3-35.
