Overview
The Stellar-Pro 300 Argon Ion Laser System is a continuous-wave (CW), air-cooled, multi-line ion laser engineered for stable, high-brightness output across the visible spectrum. Based on plasma discharge excitation within a sealed argon-filled quartz plasma tube, it generates coherent radiation primarily at 488 nm and 514.5 nm — with optional multiline operation spanning 457.9 nm, 476.5 nm, 488 nm, 496.5 nm, 501.7 nm, 514.5 nm, and 528.7 nm. Designed for laboratory-grade reliability and long-term operational stability, the system integrates a thermally stabilized plasma cavity, precision-matched Brewster-angle optics, and active current regulation to maintain ±0.5% power stability over 8 hours. Its compact, rack-mountable chassis (4U height, 19″ width) supports integration into optical tables, OEM instrumentation platforms, and automated spectroscopy workstations.
Key Features
- Multi-wavelength CW output: Standard dual-line (488/514.5 nm) or configurable multiline operation with individual line selection via internal prism or external dichroic filtering
- Air-cooled design: Eliminates need for external chiller systems; optimized thermal management enables continuous operation up to 12 hours without performance drift
- High spectral purity: Linewidth 45 dB
- Integrated digital control interface: RS-232 and USB 2.0 ports support remote power modulation, interlock monitoring, and real-time status reporting
- Compliance-ready architecture: Built-in safety interlocks, key-switched operation, and Class IV laser housing meeting ANSI Z136.1 and IEC 60825-1 requirements
- Modular beam delivery: Collimated output with adjustable divergence (±0.2 mrad), M² 100:1
Sample Compatibility & Compliance
The Stellar-Pro 300 is compatible with standard 1/2″ and 1″ optical mounts, fiber coupling adapters (FC/PC, SMA905), and OEM integration kits for OEM spectrometers, confocal microscopes, and flow cytometers. It operates within ambient temperatures of 15–30°C and relative humidity ≤ 70% non-condensing. The system conforms to FDA 21 CFR Part 1040.10/1040.11 (laser product performance standard), CE marking per Directive 2014/35/EU (Low Voltage Directive) and 2014/30/EU (EMC Directive), and is certified for use in GLP-compliant laboratories under ISO/IEC 17025-accredited environments. All firmware and hardware revisions are traceable for audit purposes, supporting full documentation of calibration history and maintenance logs.
Software & Data Management
PLASMA provides the StellarControl Suite v3.2 — a cross-platform application (Windows/macOS/Linux) for laser parameter configuration, real-time power logging, and event-triggered data capture. The software supports timestamped output records compliant with 21 CFR Part 11 requirements, including electronic signatures, audit trails, and role-based access control. Export formats include CSV, HDF5, and XML for seamless import into MATLAB, Python (via NumPy/Pandas), and LabVIEW environments. Remote operation is enabled via TCP/IP socket interface, allowing integration into centralized lab automation frameworks such as LabWare LIMS or Thermo Fisher SampleManager.
Applications

- Confocal fluorescence microscopy: Stable 488/514.5 nm lines for excitation of FITC, GFP, Alexa Fluor 488, and TRITC fluorophores
- Flow cytometry: Precise alignment and intensity control for multi-color cell sorting platforms requiring low-noise CW sources
- Optical pumping: Seed source for tunable dye lasers and Ti:sapphire amplifier systems
- Interferometry and holography: Coherence length > 20 cm enabling high-resolution phase measurements and dynamic holographic recording
- Undergraduate and graduate teaching labs: Modular design facilitates hands-on instruction in quantum optics, laser physics, and spectroscopic instrumentation
FAQ
What is the typical lifetime of the plasma tube?
The sealed argon plasma tube is rated for ≥ 5,000 operating hours under nominal current conditions (≤ 12 A), with gradual power degradation < 10% over its service life.
Can the laser be operated in single-line mode only?
Yes — internal prism rotation or external bandpass filters enable selective suppression of unwanted lines while maintaining > 90% of total available power in the selected wavelength.
Is water cooling required?
No — the Stellar-Pro 300 uses forced-air convection with dual-speed fans and heat-pipe-assisted heatsinks, eliminating dependency on external chillers.
Does the system support analog modulation?
Yes — TTL-compatible 0–5 V analog input allows external modulation of output power from 10% to 100% at bandwidths up to 10 kHz.
What safety certifications does the unit carry?
It carries CE, UKCA, and FDA registration; full compliance documentation (Declaration of Conformity, test reports) is provided with each shipment.
