Exceptional Versatility

The compact Explorer laser delivers exceptional versatility. Customers can interface with the Explorer L-Series power supply either through RS 232 software interface or via analog TTL control signals. Sophisticated software algorithms, such as Burst Mode and First-Pulse Suppression, and supporting multiple software command sets ensure straight forward product integration. Finally, the Explorer system’s rugged design enables integrating the compact laser head into a motion control system to simplify complex optical layouts.

The Explorer 1064 nm Vanadate-based (Nd:YVO4) laser provides more than 2.5 W power and is targeted for memory repair, selective ablation in thin film processes and marking applications.

Compatible Power Sensors

To verify and analyze the output power of your Explorer laser, we recommend the Ophir 15(50)A-PF-DIF-18 (7Z02740) thermal power sensor and Centauri laser power meter.  Additional information on this laser measurement equipment can be found on the website.  Other Ophir sensors and meters may also be suitable for the Explorer, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
