DMP200W 980 nm 200 W CW VCSEL Module
DMP200W provides a water-cooled 980 nm laser source for OEM heating and surface-processing equipment. At a case temperature of 25 °C, its 200 W CW optical-output operating point uses 20 A typical current and 45 V typical voltage. NTC monitoring provides a temperature-sensing input for your equipment.
Key Highlights
- Build a heating or surface-processing optical assembly around a 980 nm CW VCSEL source.
- Size the driver around the 200 W CW operating point, with 20 A and 45 V typical electrical values at Tc = 25 °C.
- Integrate the module with a water-cooling loop using 15–25 °C water at a flow rate of at least 10 L/min.
- Add temperature sensing to your control electronics through the module's NTC monitor connection.
Overview
DMP200W combines a high-power VCSEL source, water-cooled package and NTC temperature monitoring for integration into OEM laser equipment. Its 980 nm emission supports optical-source selection for laser heating and surface-processing designs.
Two CW optical-output operating points are provided at Tc = 25 °C. At 200 W, the typical current and voltage are 20 A and 45 V. At 30 W, they are 8 A and 42 V. Use the operating point relevant to your design when planning the driver and cooling system.
Typical irradiation footprint dimensions are 6 × 6 cm at a distance of 6 cm and 6.5 × 6.5 cm at 10 cm. These dimensions help you plan the target position and optical assembly. The module’s plan-view outline is 75 × 65 mm, with separate laser and NTC connections.

Integration
Driver and cooling
Select a current-regulated driver around the chosen CW operating point. Include voltage headroom, cable losses, startup and shutdown behavior in the electrical design, and provide surge protection for the laser.
Connect the module to a cooling loop that delivers 15–25 °C water at at least 10 L/min. Plan hose routing, mounting access and temperature monitoring together with the driver and equipment controls.
Optical assembly and handling
Set the target position and delivery optics around the required exposure area. Measure delivered optical power and the beam profile at the equipment’s working plane as part of process setup.
Use the package outline for mechanical planning. Follow grounded, ESD-controlled handling practices for personnel and equipment. Include optical shielding, access controls and laser-safety review in the complete equipment design.
