Overview
The Keopsys PGFL Series is a high-performance, diode-pumped solid-state (DPSS) pulsed green laser source engineered for precision optical measurement and industrial sensing applications requiring stable, visible-wavelength nanosecond pulses. Operating at a fundamental wavelength of 532 nm—generated via intracavity frequency doubling of a 1064 nm Nd:YAG or Nd:YVO₄ oscillator—the PGFL delivers diffraction-limited beam quality (M² < 1.3), enabling tight focusability and high spatial resolution in demanding metrology environments. Its all-solid-state architecture eliminates reliance on liquid dyes or gas media, ensuring long-term stability, low maintenance, and immunity to thermal drift under continuous operation. Designed as an OEM module, the PGFL integrates seamlessly into embedded systems where size, power efficiency, and mechanical robustness are critical—particularly in field-deployable instruments operating in marine, aerial, or ruggedized terrestrial conditions.
Key Features
- Stable 532 nm output with pulse-to-pulse energy stability better than ±3% (RMS) over 8 hours, validated per ISO 11554 calibration protocols
- Nanosecond pulse duration (typ. 1–5 ns FWHM), optimized for time-of-flight (ToF) ranging and fluorescence lifetime excitation
- Adjustable repetition rate from 10 kHz to 200 kHz via TTL or analog voltage control, supporting flexible duty-cycle optimization
- Integrated thermoelectric cooler (TEC) and PID-controlled temperature stabilization (±0.1 °C), ensuring wavelength stability within ±0.05 nm across ambient temperatures from 10 °C to 40 °C
- Compact hermetically sealed housing (120 × 80 × 35 mm) with SMA905 or FC/PC fiber-coupled output options (optional)
- Low power draw (< 25 W @ 24 V DC input), compliant with EN 61000-6-3 for conducted emissions and EN 61000-6-2 for immunity
Sample Compatibility & Compliance
The PGFL is compatible with standard optical components rated for 532 nm CW and pulsed irradiance (up to 1 GW/cm² peak intensity). Its Class 4 laser classification per IEC 60825-1:2014 mandates integrated safety interlocks, key-switch enable, and emission indicator LED—fully configurable for integration into larger systems meeting FDA 21 CFR Part 1040.10 and EU Machinery Directive 2006/42/EC requirements. The device conforms to RoHS 2011/65/EU and REACH SVHC regulations. For GLP/GMP-aligned deployment, optional factory calibration certificates traceable to LNE (Laboratoire National de Métrologie et d’Essais, France) are available upon request.
Software & Data Management
While the PGFL operates as a stand-alone hardware module, it supports full external control via RS-232 or USB-C serial interface using ASCII command protocol (e.g., “REP 50000” sets 50 kHz repetition rate). Keopsys provides a Windows-based configuration utility (PGFL Control Suite v2.1) with real-time monitoring of diode current, TEC voltage, internal temperature, and pulse energy (via optional integrated photodiode feedback). All operational parameters—including trigger delay, burst mode settings, and safety lockout status—are logged with UTC timestamps and exportable as CSV for audit trails. The firmware supports SCPI-like syntax and is compatible with LabVIEW™, Python (pySerial), and MATLAB® instrument control toolboxes—enabling synchronization with oscilloscopes, data acquisition systems, or motion controllers in automated test benches.
Applications
- Underwater telemetry and range-finding: High transmission efficiency of 532 nm in clear seawater enables sub-meter ranging accuracy at depths exceeding 30 m in coastal waters
- High-speed 3D topographic scanning: Sub-5 ns pulse width and < 100 ps timing jitter support sub-millimeter depth resolution in multi-return LiDAR configurations
- Fluorescence lifetime imaging (FLIM) and time-resolved spectroscopy: Precise pulse triggering and low jitter facilitate TCSPC (time-correlated single-photon counting) setups
- Remote sensing and environmental monitoring: Used in airborne bathymetric mapping systems compliant with ASTM E2773–19 for shallow-water elevation modeling
- Micromachining and laser-induced breakdown spectroscopy (LIBS): Sufficient peak power for ablation of non-metallic substrates including polymers, ceramics, and biological tissue
FAQ
Is the PGFL suitable for integration into portable or battery-powered systems?
Yes—the module’s 4 hours of continuous operation at 50 kHz rep rate.
Does Keopsys provide beam profiling data and M² measurement reports?
Yes—each unit ships with a factory-measured beam parameter product sheet, including caustic curve, beam waist location, Rayleigh range, and ISO 11146-compliant M² calculation.
Can the laser be synchronized with external detectors or cameras?
Yes—TTL-compatible sync output (rise time < 2 ns) is provided on SMA connector, with programmable delay (0–100 µs, 10 ns resolution) relative to pulse emission.
What cooling method is required for sustained operation?
The integrated TEC and heatsink support continuous operation without forced air; however, for ambient temperatures above 35 °C or duty cycles > 50%, passive finned heatsinking or low-noise fan cooling is recommended.
Is FDA or IEC 60825 certification documentation included?
Yes—CE Declaration of Conformity, IEC 60825-1 test report (per SGS or Bureau Veritas), and laser safety manual are supplied with every shipment.
