Frequently Asked Questions
01 - Do I need an optical isolator?
An optical isolator prevents back-reflections from destabilising the laser cavity. For NIR free-space configurations, an isolator is systematically recommended. FC/APC fiber connectors provide inherent back-reflection suppression and may be sufficient for visible/fiber-coupled setups.
02 - Do I need fiber coupling, and which fiber type?
- SM (single-mode): diffraction-limited beam quality — for confocal and precision setups.
- PM (polarisation-maintaining): preserves polarisation state — for polarisation-sensitive experiments.
- MM (multi-mode): higher power delivery with relaxed spatial requirements.
Fiber length and connector type (FC/APC, FC/PC, SMA…) must be confirmed to match your instrument.
Note: If you are not experienced with SM/PM fiber injection, the Exoskeleton option provides a pre-aligned, mechanically stable assembly.
03 - Do I need modulation and which mode is right for me?
- MPA (Modulated Power Adjustment): analogue power control. Best for variable illumination without high-speed switching.
- AOM (Acousto-Optic Modulator): high-frequency switching up to 20 MHz. Required for FRAP, photoactivation, time-gated detection, spinning-disk confocal.
For DPSS models (532, 553, 561 nm), modulation requires the L1C or L1C+ driver combined with MPA or AOM — the DPSS gain medium cannot be directly modulated at high speed.
04 - Is a heatsink required?
For FlexxRay lasers above 300 mW, an external heatsink is required to ensure stable operation and long-term reliability. For OEM integrations, thermal interface design must be addressed in the early mechanical design phase.
05 - PP (lab) or OEM version?
- PP (laboratory): plug-and-play unit with standard connectors, ready for immediate use in a research environment.
- OEM: compact form factor for system integrators. Requires the integrator to manage power supply, thermal management and control interfaces.
Note: For OEM configurations, output power stability must be addressed early — thermal design and mounting conditions directly affect long-term performance.
06 - What beam quality can I expect?
FlexxRay delivers a TEM00 Gaussian beam — the tightest focus, highest brightness, best fiber coupling efficiency. Optical noise is as low as ≤0.2 % rms (10 Hz–20 MHz), ideal for quantitative fluorescence and spectroscopy.
07 - What is the difference between a diode laser and a DPSS laser?
Oxxius uses two complementary technologies in FlexxRay. Understanding the difference is key to choosing the right model:
| Laser diode (LBX) | DPSS (LCX / LPX) | |
| Principle | Direct semiconductor emission | Diode-pumped solid-state crystal, frequency-converted |
| Wavelengths | Broad UV-NIR (375–1064 nm) | Specific visible lines: 532, 553, 561, 607 nm |
| Linewidth | ≤1.5–2 nm (multimode) | ≤0.1–0.5 nm — much narrower |
| Modulation | Direct current — fast and simple | Requires L1C/L1C+ driver + MPA or AOM |
| Warm-up | Short | Longer — crystal requires thermal stabilisation |
| Best for | Fluorescence microscopy, flow cytometry, OEM, NIR | Raman, applications requiring 532/561 nm with tight linewidth |
Note: If your application requires 532, 553, or 561 nm (or demands sub-nm spectral purity) you need a DPSS model. For all other wavelengths and fast modulation requirements, a diode laser is the more efficient choice.
08 - Which wavelength and power level should I choose?
FlexxRay covers 375–1064 nm with over 30 wavelengths, from 40 mW to 1000 mW. Key pointers:
- Fluorescence microscopy: standard lines are 405, 445, 488, 515, 532, 561, 638 nm.
- Raman spectroscopy: 532 nm (DPSS) or 785 nm are the most common choices.
- NIR applications: 785–1064 nm options available.
Our team can help select the optimal wavelength based on your dyes, samples or instrument requirements.
