Overview
The Onefive Katana-HP is a high-reliability, multi-wavelength pulsed laser system engineered for demanding industrial and scientific applications requiring stable, turnkey ultrafast excitation sources. Based on a hybrid architecture—integrating fiber-integrated seed oscillators with bulk solid-state amplification—the Katana-HP delivers exceptional pulse fidelity, high peak power, and long-term amplitude stability without active alignment or periodic maintenance. Its core operating principle relies on mode-locked solid-state gain media (e.g., Nd:YVO₄, Yb-doped crystals) combined with nonlinear frequency conversion (SHG, THG, OPO) to generate discrete, user-selectable wavelengths across UV, visible, and NIR spectral bands. Unlike conventional diode-pumped solid-state (DPSS) lasers, the Katana-HP’s proprietary thermal management and mechanical isolation design ensure sub-1.3 M² beam quality and <4.0% RMS amplitude noise over 10-hour continuous operation—critical for quantitative fluorescence lifetime imaging (FLIM), stimulated emission depletion (STED) microscopy, and precision laser processing where pulse-to-pulse consistency directly impacts measurement reproducibility and feature resolution.
Key Features
- Multi-wavelength flexibility: Standard output at 266 nm, 355 nm, 515–532 nm, 556–660 nm, 775 nm, 1030–1064 nm, 1112–1320 nm, and 1550 nm—enabling single-platform support for multi-channel spectroscopy, multi-color super-resolution imaging, and wavelength-matched material ablation.
- Wide pulse parameter tunability: Pulse duration adjustable from 30 ps to 10 ns depending on model; repetition rate continuously variable from single-shot to 100 MHz via internal clock synthesis or external TTL/LVDS triggering.
- Industrial-grade robustness: Qualified per IEC 60068-2-6 (sinusoidal vibration), IEC 60068-2-27 (shock), and IEC 60068-2-29 (repetitive shock); rated for 24/7 operation across 15–35 °C ambient without performance drift or intermittent pulse dropout.
- Turnkey operation: No optical realignment required; factory-optimized cavity stabilization ensures 10,000 on/off cycles).
- Modular architecture: Optional add-ons include integrated Faraday isolators, collimated free-space output, burst-mode sequencing (user-defined pulse trains), and custom spectral filtering—facilitating integration into OEM instrumentation and automated production lines.
Sample Compatibility & Compliance
The Katana-HP is designed for direct integration into regulated analytical and manufacturing environments. Its optical output meets Class IV laser safety requirements per IEC 60825-1:2014 and FDA 21 CFR Part 1040.10. All models comply with CE marking directives (EMC 2014/30/EU, LVD 2014/35/EU) and RoHS 2011/65/EU. For laboratories operating under GLP or GMP frameworks, the system supports traceable operational logs via RS232/Ethernet interface, enabling audit-ready documentation of runtime, temperature history, and trigger event timestamps. While not inherently 21 CFR Part 11-compliant, the controller firmware allows third-party integration with validated electronic lab notebook (ELN) or LIMS platforms for full electronic record integrity.
Software & Data Management
Onefive provides the Katana Control Suite—a cross-platform (Windows/macOS/Linux) application enabling full remote configuration of pulse parameters, monitoring of thermal and power diagnostics, and synchronization with external timing systems (e.g., DAQ cards, microscope scan controllers). The software exposes a documented ASCII-based serial protocol and TCP/IP API, permitting script-driven control in Python, MATLAB, or LabVIEW environments. Real-time amplitude and temperature telemetry are logged at 1 Hz resolution with optional CSV export. Firmware updates preserve all user-defined presets and maintain backward compatibility across hardware revisions—ensuring long-term deployment stability in research infrastructure and production tooling.
Applications
- Super-resolution microscopy: STED, RESOLFT, and gated STED implementations benefit from the Katana-HP’s diffraction-limited beam profile, high PER (>23 dB), and jitter-free external triggering—enabling precise depletion pulse alignment relative to excitation pulses.
- Time-resolved fluorescence spectroscopy: Nanosecond-to-picosecond pulse widths support TCSPC and streak camera measurements across UV–NIR detection ranges, with low amplitude noise ensuring high signal-to-noise ratio in weak-emission samples.
- Laser micromachining: High peak power (>400 kW) and wavelength versatility enable selective ablation of thin-film solar cells (e.g., P1/P2/P3 scribing at 1064 nm or 532 nm), transparent conductor patterning, and polymer surface structuring.
- LIDAR and time-of-flight sensing: Sub-nanosecond timing precision, combined with air-cooled compactness, supports portable rangefinding systems requiring high pulse energy and low SWaP-C (Size, Weight, Power, and Cost).
- Nonlinear optics pumping: Stable fundamental output at 775 nm or 1064 nm serves as efficient pump source for OPOs, OPAs, and harmonic generation stages in ultrafast spectroscopy setups.
FAQ
Is the Katana-HP compatible with existing microscope scan engines and timing controllers?
Yes—the laser supports TTL, LVDS, and programmable delay inputs with <1 ns jitter, and integrates natively with major OEM platforms including Thorlabs, Nikon, Leica, and Zeiss via standard trigger protocols.
Can pulse width and repetition rate be adjusted independently for a given wavelength?
Yes—each model offers independent tuning of pulse duration and repetition rate within its specified range; however, maximum pulse energy and average power are interdependent and governed by thermal limits defined in the datasheet.
Does the system require water cooling or external chillers?
No—all Katana-HP variants operate exclusively with passive or forced-air cooling; no liquid cooling infrastructure is needed, simplifying installation in cleanrooms and mobile labs.
What is the expected lifetime of the laser gain medium and pump diodes?
Based on accelerated lifetime testing per Telcordia GR-468-CORE, the pump diodes and crystalline gain elements are rated for >20,000 hours of continuous operation under nominal conditions.
Are OEM integration kits and mechanical mounting interfaces available?
Yes—Onefive offers standardized kinematic mounts, beam-height adapters, and electrical harnesses with MIL-spec connectors; custom mechanical and optical interfaces can be developed under NDA for volume OEM deployments.
