Overview
The Evolase UKKO-PS and UKKO-NS series are engineered high-repetition-rate picosecond and nanosecond fiber laser systems designed for precision scientific, industrial, and biomedical applications. Based on all-fiber master oscillator power amplifier (MOPA) architecture, these lasers deliver exceptional temporal stability, low timing jitter, and high pulse-to-pulse energy reproducibility—critical for nonlinear optical pumping, time-resolved spectroscopy, and high-fidelity micromachining. The UKKO-PS operates with a fixed pulse duration of approximately 50 ps at fundamental (1064 nm), second-harmonic (532 nm), and third-harmonic (355 nm) outputs, while the UKKO-NS offers tunable nanosecond pulse generation across a broad repetition rate range (10 Hz to 10 MHz), supporting both free-space and polarization-maintaining fiber delivery. Both platforms integrate thermally optimized pump diode arrays and all-fiber seed amplification paths to ensure long-term reliability and minimal maintenance under continuous operation.
Key Features
- Ultra-compact monolithic design (< 300 × 200 × 90 mm for UKKO-PS base unit), enabling integration into space-constrained optical tables and OEM instrumentation.
- High wall-plug efficiency (>25% typical for UKKO-PS at 1064 nm), reducing thermal load and eliminating need for external chiller units in most lab environments.
- Digital pulse control via USB 2.0 and RS-232 interfaces, supporting external TTL triggering, burst-mode operation, and real-time repetition rate modulation.
- Integrated beam collimation and optional harmonic separation optics—pre-aligned and factory-qualified for stable multi-wavelength output.
- Passive and active cooling architectures compliant with ISO 10110-7 surface quality and IEC 61228 stability requirements for Class 4 laser systems.
Sample Compatibility & Compliance
These lasers are compatible with standard fused silica, BK7, CaF2, and sapphire optical components rated for >5 GW/cm² peak intensity (UKKO-PS). Beam delivery supports SMF-28e+, PM980, or HI1060 fiber coupling with FC/APC or SMA905 connectors. All units conform to IEC 60825-1:2014 for laser safety classification (Class 4), carry CE marking per EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU, and meet RoHS 2011/65/EU substance restrictions. For regulated environments—including GLP-compliant analytical labs and medical device R&D—the UKKO series supports optional audit-trail-enabled firmware (compatible with FDA 21 CFR Part 11–compliant data acquisition software).
Software & Data Management
Evolase provides the UKKO Control Suite—a cross-platform application (Windows/Linux/macOS) for real-time parameter monitoring, pulse train visualization, and automated calibration logging. The suite exports timestamped datasets in HDF5 and CSV formats, with metadata fields aligned to MIAME and FAIR data principles. API support (C/C++, Python SDK, LabVIEW VIs) enables seamless integration into custom DAQ systems, including those compliant with ASTM E2917-21 (standard practice for laser-based dimensional metrology). Firmware updates preserve configuration history and include cryptographic signature verification to satisfy GMP traceability requirements.
Applications
- Volume inscription and subsurface modification of transparent dielectrics (e.g., fused silica, borosilicate glass) for photonic device fabrication and anti-counterfeiting features.
- Precision ablation of brittle materials (sapphire, silicon carbide, ceramics) with minimized heat-affected zones—validated per ISO 11146-2 beam propagation analysis.
- Pumping of optical parametric oscillators (OPOs) and amplifiers (OPAs) for ultrafast spectroscopy in the mid-IR (2–12 µm).
- Time-gated fluorescence lifetime imaging (FLIM) and multiphoton microscopy, leveraging sub-100 ps timing resolution for FRET and anisotropy decay studies.
- Laser-induced breakdown spectroscopy (LIBS) and stimulated Raman scattering (SRS) systems requiring high peak power and shot-to-shot stability.
FAQ
What is the maximum average power available at 355 nm for the UKKO-PS system?
Up to 12 W is achievable with optional harmonic enhancement optics and thermal management upgrades—subject to beam quality verification per ISO 13694.
Can the UKKO-NS be synchronized to an external clock source with sub-nanosecond jitter?
Yes—via low-jitter (< 50 ps RMS) 10 MHz reference input; phase-locking to femtosecond oscillators is supported using the optional RF synchronization module.
Is remote diagnostics and predictive maintenance supported?
All UKKO systems include embedded telemetry (temperature, pump current, cavity alignment status) accessible via Ethernet; cloud-based analytics require customer-deployed secure gateway per ISO/IEC 27001 guidelines.
Are custom wavelength combinations available beyond the standard harmonics?
Yes—Evolase offers OEM co-design services for tailored spectral outputs (e.g., 940 nm, 1550 nm, or dual-wavelength burst modes), subject to feasibility assessment and minimum order volume.
