What to Include in a 1535 nm Laser Source RFQ
Most enquiries take three emails before we can quote. The ones that do not share one thing: they answer five questions in the first message.
1. The application
Rangefinding, designation, LiDAR, or sensing. This decides whether the energy budget is set by a cooperative target at short range or an uncooperative one at long range, and it changes the model by an order of magnitude.
2. Energy you need at the target, and against what
"3 km" alone is not enough — a road sign and a matte vehicle at the same distance are different problems. Give the target size and reflectivity, or at least the type. If you do not know the number yet, say what the receiver is and we can work backwards.
3. Repetition rate
How often the system needs a measurement, and whether the rate is fixed or adaptive. Above roughly 100 Hz the choice moves to the high-repetition family and the energy per pulse drops by an order of magnitude.
4. The power you can provide
Supply voltage and peak current available at the module. A 20 A rail cannot run a 100 A transmitter, and this constraint rules out models faster than the optics do.
5. Aperture and environment
The window size your optics allow, the operating temperature range, and whether the unit has to survive shock and vibration. Aperture sets the divergence floor; temperature and vibration decide the screening the unit needs.
What to leave out of the first message
You do not need to pick a model, specify the interface, or commit to a quantity to get a useful answer. Model choice is our job once the five items above are on the table.
For custom and OEM programmes
Add two things: what the system looks like today (an existing part, a competitor module, or nothing yet), and who owns the interface on your side — mechanical, electrical or optical. That determines whether the answer is a variant of a catalogue model or a new design.
