Overview
The MPB newopto Visible Fiber Laser is a high-stability, single-frequency diode-pumped fiber laser system engineered for precision applications in life sciences, analytical instrumentation, and industrial metrology. Operating across the visible spectrum—from 488 nm to 670 nm—the laser leverages robust all-fiber architecture to deliver diffraction-limited (TEM₀₀) output with exceptional spectral purity and long-term wavelength stability of ±0.02 nm. Unlike free-space solid-state lasers, this fiber-integrated platform eliminates alignment sensitivity, minimizes thermal drift, and ensures consistent beam pointing over extended operation cycles. Its collimated, linearly polarized output—combined with M² < 1.1 and divergence < 5 mrad—enables seamless integration into demanding optical trains, including confocal microscopes, flow cytometers, and interferometric metrology setups. Designed and manufactured in Canada, the system complies with IEC 60825-1:2014 safety standards for Class 3B/4 laser products and meets RoHS and REACH environmental compliance requirements.
Key Features
- Wide visible wavelength selection: 488, 514, 532, 542, 546, 560, 570, 580, 589, 592, 620, 628, 642, 647, and 670 nm—each available in multiple power variants (200–2000 mW)
- High spectral stability: ±0.02 nm RMS wavelength drift over 8 hours at constant ambient temperature (23 ± 1 °C)
- Continuous-wave (CW) operation with analog and digital modulation inputs (TTL & 0–5 V), supporting external intensity control from 20% to 100% of rated output
- Diffraction-limited beam quality: TEM₀₀ mode with M² < 1.1 and near-perfect Gaussian intensity profile
- Integrated thermoelectric cooler (TEC) and PID-controlled driver for low-noise current regulation and sub-milliwatt power repeatability
- Robust mechanical housing with industry-standard 19 mm diameter fiber output port (FC/APC or FC/PC connector options)
- Compliance with FDA 21 CFR Part 1040.10/1040.11 for laser product safety reporting and labeling
Sample Compatibility & Compliance
The MPB newopto Visible Fiber Laser is compatible with standard single-mode optical fibers (SMF-28, HI1060) and integrates directly with OEM optical subsystems requiring stable visible excitation. Its output meets ISO 11146-1:2005 beam parameter measurement standards and supports GLP/GMP-aligned workflows through traceable calibration certificates (available upon request). The system conforms to CE marking directives (2014/35/EU Low Voltage Directive and 2014/30/EU EMC Directive), and its enclosure design satisfies IP52 ingress protection for laboratory environments. For regulated biophotonics applications—including clinical flow cytometry and diagnostic fluorescence imaging—the laser’s narrow linewidth (< 0.1 nm), low relative intensity noise (< –120 dB/Hz at 1 MHz), and absence of mode hops ensure reproducible signal-to-noise ratios essential for quantitative assay validation per CLSI EP17-A2 and ISO 15197:2013.
Software & Data Management
The laser operates via embedded firmware with RS-232 and USB-C communication interfaces, enabling full remote control using MPB’s proprietary LaserControl Suite (Windows/Linux/macOS). The software provides real-time monitoring of output power, diode temperature, TEC status, and interlock conditions, with timestamped logging compliant with FDA 21 CFR Part 11 requirements—including electronic signatures, audit trails, and data integrity safeguards. All operational parameters are stored in non-volatile memory and can be exported in CSV or HDF5 format for LIMS integration. Optional SDKs (C/C++, Python, LabVIEW) support custom automation in high-throughput screening platforms and closed-loop optical feedback systems.
Applications
- Confocal and super-resolution fluorescence microscopy (e.g., STED, SIM) requiring stable multi-wavelength excitation
- Flow cytometry instrumentation—especially dual-laser and spectral cytometers needing precise 532 nm, 561 nm, or 642 nm lines
- Raman spectroscopy excitation sources where visible wavelengths enhance resonance effects in biological and pharmaceutical samples
- Laser-based particle image velocimetry (PIV) and Doppler anemometry in fluid dynamics research
- Calibration of photodetectors, spectrometers, and radiometric sensors traceable to NIST standards
- Photopolymerization and selective laser sintering (SLS) processes requiring tightly focused, high-brightness visible beams
