Ekspla Atlantic HR High-Repetition-Rate Industrial Picosecond Laser System

Overview

The Ekspla Atlantic HR is a high-repetition-rate, diode-pumped solid-state (DPSS) picosecond laser system engineered for demanding industrial and scientific applications requiring exceptional temporal precision, spectral stability, and long-term operational reliability. Operating on the principle of mode-locked Nd:YVO₄ or Nd:YAG gain media with nonlinear harmonic generation, the Atlantic HR delivers sub-8-picosecond pulses at fundamental (1064 nm), second-harmonic (532 nm), and third-harmonic (355 nm) wavelengths. Its core architecture integrates a monolithic oscillator-amplifier configuration with active thermal management and vibration-damped mechanical design—ensuring pulse-to-pulse amplitude stability better than ±0.7% RMS over 8 hours and pointing stability < 5 µrad. Designed explicitly for integration into automated production lines and ultrafast optical laboratories, the Atlantic HR complies with IEC 60825-1:2014 Class 4 laser safety standards and meets CE marking requirements for electromagnetic compatibility (EMC) and low-voltage directives.

Key Features

• Industrial-grade sealed cavity design eliminates sensitivity to ambient dust, humidity, and minor pressure fluctuations—enabling uninterrupted operation in factory-floor environments.
• Single-phase 230 V AC input eliminates dependency on three-phase infrastructure or external chiller systems; thermoelectric and forced-air hybrid cooling maintains junction temperature within ±0.1°C tolerance.
• Real-time internal diagnostics monitor pump diode current, cavity alignment status, harmonic conversion efficiency, and pulse energy drift—accessible via RS-232/USB/Ethernet interfaces.
• Beam delivery interface conforms to ISO 10110-3 standard optics mounting (M30×1 threaded flange) with integrated beam height adjustment and collimation verification port.
• Optional integrated pulse picker (electro-optic or acousto-optic) enables user-selectable repetition rate reduction from 88 MHz down to single-shot, preserving pulse energy and temporal profile integrity.

Sample Compatibility & Compliance

The Atlantic HR is compatible with a broad range of optically transparent and absorbing materials—including fused silica, sapphire, silicon carbide, copper, stainless steel, polyimide, and photoresists—without requiring vacuum chambers or inert gas purging. Its short pulse duration minimizes heat-affected zones (HAZ) during ablation, enabling feature resolution below 10 µm in thin-film patterning. The system supports compliance workflows aligned with ISO 9001:2015 quality management protocols and provides full traceability logs required for ISO/IEC 17025-accredited calibration laboratories. For regulated manufacturing environments (e.g., medical device component fabrication), optional firmware modules enable audit-ready electronic records per FDA 21 CFR Part 11 and EU Annex 11 guidelines.

Software & Data Management

Control is managed through Ekspla’s proprietary Laser Control Suite (LCS v4.2), a Windows-based application supporting remote operation, script-driven parameter sequencing, and synchronized triggering with motion stages or cameras via TTL/PECL-compatible digital I/O. LCS generates timestamped binary data files (.lcsbin) containing full pulse energy history, wavelength calibration coefficients, thermal sensor readings, and interlock event logs. Export formats include CSV, HDF5, and MATLAB .mat for post-processing in MATLAB, Python (NumPy/H5Py), or LabVIEW environments. All software binaries are digitally signed and validated against SHA-256 checksums; update packages undergo static code analysis prior to release.

Applications

• Precision micromachining: Drilling micro-vias in PCB substrates, cutting stent struts, and scribing thin-film solar cells with minimal recast layer formation.
• Nonlinear frequency conversion seeding: Serving as master oscillator for optical parametric amplifiers (OPAs) and optical parametric oscillators (OPOs) requiring high-repetition-rate, narrow-jitter pump sources.
• Time-resolved spectroscopy: Enabling pump-probe experiments in condensed matter physics labs where timing jitter < 30 fs RMS is critical for carrier dynamics analysis.
• Surface structuring: Generating laser-induced periodic surface structures (LIPSS) on titanium alloys for biomedical implant texturing, with reproducible spatial period control within ±2% variation.
• In-line process monitoring: Integration with machine vision systems for real-time ablation depth feedback using back-reflected pulse energy normalization algorithms.

FAQ

Is the Atlantic HR suitable for cleanroom environments?
Yes—the fully sealed optical path and absence of consumables or open coolant loops meet ISO Class 5 (Class 100) cleanroom compatibility requirements when installed with appropriate HEPA-filtered air intake.
Can output wavelength be switched during operation?
Wavelength selection (1064/532/355 nm) is manually configured via internal harmonic separator alignment and requires recalibration; it is not dynamically tunable in real time.
What is the expected lifetime of the pump diodes?
Rated mean time between failures (MTBF) exceeds 20,000 hours under continuous operation at nominal power settings, verified per Telcordia GR-468-CORE reliability testing standards.
Does the system support external synchronization?
Yes—standard BNC inputs accept external trigger signals (TTL/CMOS) for master-slave synchronization with femtosecond amplifiers or delay generators, with jitter < 150 ps RMS.
Is service documentation available in English?
Full technical manuals—including safety instructions, maintenance procedures, spare parts catalog, and firmware update guides—are provided in English PDF format with searchable indexing and revision-controlled version stamps.
