Frequently Asked Questions
01 - Do I need modulation capability?
MaxxPower diode lasers can be modulated directly via drive current at moderate speeds.
02 - Is a heatsink mandatory?
Yes! For all models above 300 mW. At power levels exceeding 1 W, inadequate thermal dissipation leads to power drift, degraded performance, or shutdown. For OEM integrations, thermal interface design must be part of the mechanical design from the outset.
03 - MaxxPower is a diode laser range: how does it differ from DPSS?
The MaxxPower lasers are exclusively based on laser diode technology. Here is what that means for your application:
| Laser diode (MaxxPower LBX) | DPSS (FlexxRay / StaxxBeam LCX/LPX) | |
| Power levels | Up to 1400 mW — highest in portfolio | Up to 800 mW — optimised for precision |
| Beam profile | Multimode — wider, less focused | TEM00 — diffraction-limited |
| Linewidth | ≤2 nm — sufficient for fluorescence | ≤0.1–0.5 nm — for Raman, Brillouin |
| Modulation | Direct current — fast, simple | Requires L1C/L1C+ + MPA or AOM |
| Warm-up | Very short | Longer crystal stabilisation |
| Best for | High-power excitation, optogenetics, OEM | Spectroscopy, precision imaging, coherence-sensitive |
Note: MaxxPower is the right choice when you need maximum photon flux at the sample and beam quality is not the limiting factor. For diffraction-limited spots or tight spectral linewidth, consider FlexxRay (CW and modulated lasers) or StaxxBeam (single-frequency lasers).
04 - 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.
05 - What fiber coupling options are available?
Available in free-space or fiber-coupled configurations. For fiber, confirm: SM / PM / MM type (MM is most common for high-power diodes), fiber length, and connector type (FC/APC, FC/PC, SMA…).
Note: For SM or PM injection, the Exoskeleton option is strongly recommended for users without fiber coupling experience.
06 - What laser safety class do these modules fall into?
At 200 mW to 1400 mW, MaxxPower modules typically fall into Class 3B or Class 4 depending on wavelength and configuration. Mandatory precautions include appropriate laser safety eyewear, interlocked enclosures, and full compliance with your institution’s laser safety policy. Always consult your laser safety officer before installation and operation.
07 - What wavelength and power level do I need?
MaxxPower covers 375–980 nm with 13 wavelength options, from 200 mW up to 1400 mW. When sizing power, account for all optical losses: fiber coupling efficiency, beam splitters, objective transmission, and dichroic filters — the power at the sample is often significantly lower than the laser output specification.
08 - Which applications benefit most from MaxxPower?
- Optogenetics and photoactivation requiring high photon flux at the sample plane.
- Flow cytometry with high-speed detection needing bright excitation.
- Widefield fluorescence imaging with weakly absorbing dyes.
- OEM instrument integration where compactness and power must coexist.
- Industrial sensing, material processing, or pumping applications.
