A high-power 980 nm VCSEL module for OEM laser heating and surface-processing equipment. The datasheet documents 200 W and 30 W CW operating points at Tc = 25 °C, with water cooling and NTC temperature monitoring.
Key Highlights
DMP200W is a water-cooled, high-power 980 nm vertical-cavity surface-emitting laser (VCSEL) module for OEM equipment integration. Its reference datasheet documents 200 W and 30 W continuous-wave (CW) optical-output operating points at Tc = 25 °C. It lists laser heating, surface processing and medical cosmetology as application areas.
At the 200 W CW operating point, drive current is 20 A typical / 24 A maximum and operating voltage is 45 V typical / 50 V maximum. The cooling-water requirement is 15-25 °C at a flow rate of at least 10 L/min. These are component integration conditions, not a specification for a complete laser system.
Selection boundary: The two documented CW points do not establish a qualified 30-200 W adjustment range or a pulsed operating specification. The irradiation dimensions below describe target-plane coverage, not package size, field of view or beam uniformity.
Technical reference: DOMI-DMP200W, Rev. 1.1, dated 19 April 2025; features and applications on p. 2, operating data on p. 3, outline on p. 4, handling precautions on p. 5. Confirm the orderable DMP200W configuration and current revision with DOMI before design release.
The following application areas are listed in the reference datasheet. They are starting points for system evaluation, not claims of qualified process performance.
Read the conditions with the values. Typical values are reference characteristics. Values in the Max column below are maxima in the electro-optical table, not a separate absolute-maximum-ratings specification. A dash means no value is stated.

| Cooling package | Water-cooled | External cooling-loop requirements must be met. |
| Operating ambient temperature (TOPR) | 15-40 °C | The datasheet explicitly defines this as environment temperature. |

| Irradiation footprint dimensions (A) | Distance = 10 cm | – | 6.5 × 6.5 | – | cm × cm |
Optical-data limitation: The source calls the footprint rows “Laser Irradiation Area” and gives two side lengths with unit cm; they are expressed here as cm × cm for clarity. The power-intensity rows do not identify a measurement distance, averaging method or uniformity criterion. Do not assign 4 W/cm² to the 10 cm plane or infer a beam profile from these separate rows.
| Function | Specified value | Not supplied in this revision |
|---|---|---|
| NTC temperature monitoring | B value = 3930 K | R25, resistance tolerance, B-value temperature interval, calibration accuracy and connector specification. |
980 nm and B = 3930 K are feature/monitor values, not values placed in a Min/Typ/Max table by the source. No tolerance or accuracy is implied.
The outline drawing on p. 4 provides the following reference dimensions and connection labels. Use a confirmed interface drawing for mounting and routing; the target-plane irradiation footprint is not the module footprint.
| Drawing item | Reference / interpretation |
|---|---|
| Plan-view outline | 75 × 65 mm. |
| Side-view height callout | <22 mm across the indicated body section; not an overall envelope including hoses, fittings or leads. |

The first item below summarizes the datasheet precautions. The remaining items are engineering review recommendations, not additional guaranteed product specifications.
The datasheet warns that electrostatic discharge (ESD), electrical overstress (EOS) and electrical surges can damage the laser and degrade performance. Use driver surge protection, proper equipment/personnel grounding and an ESD-controlled handling process, including suitable ionization and antistatic equipment.
200 W denotes the documented optical-output point, not electrical input power. Review current regulation, voltage headroom, startup/shutdown behavior, transients and cable losses with the intended driver. Do not use the listed 24 A or 50 V maxima as independent safe operating limits, or infer pulse current and duty-cycle ratings from CW data.
Verify that the module cooling path meets 15-25 °C water temperature and ≥10 L/min flow in the installed system. Obtain pressure-drop, coolant-quality and fitting requirements before selecting the pump and plumbing. Request NTC R25, tolerances and calibration information before setting measurement or shutdown thresholds.
Measure delivered power and beam profile at the intended working distance. Include laser-safety review, enclosure/interlock design and thermal/flow fault handling in the system validation plan. This datasheet does not state a laser safety class, divergence angle, uniformity specification, lifetime, IP rating or product certification.
At Po = 200 W CW and Tc = 25 °C, current is 20 A typical / 24 A maximum and voltage is 45 V typical / 50 V maximum. At Po = 30 W CW under the same Tc condition, they are 8 A / 10 A and 42 V / 46 V respectively. These are electro-optical table values, not absolute-maximum ratings.
Cooling-water temperature is 15-25 °C and the minimum flow rate is 10 L/min. The operating ambient range is separately specified as 15-40 °C; storage is 5-85 °C. Confirm coolant quality, pressure drop and plumbing interfaces for the selected configuration.
Typical footprint dimensions are 6 × 6 cm at a 6 cm distance and 6.5 × 6.5 cm at a 10 cm distance. These are not package dimensions or a uniformity specification. The separate power-intensity values have no stated measurement distance.
