Features
It’s in the Box™ Design
The Millennia platform is based on Spectra-Physics’ It’s in the Box™ design, where the laser optical cavity,diode and control electronics are all integrated in a single, compact package, eliminating the need for an external power supply.
Millennia eV benefits from Spectra-Physics’ extensive experience in the design of rugged industrial lasers. Millennia eV lasers utilize long life, highly reliable laser diodes. The result is a highly reliable laser, ensuring dependable, easy turnkey operation with exceptional value.
With its industry leading scalability from 5 W to 25 W average power and high reliability, Millennia eV is the laser of choice for demanding scientific applications such as the pumping of high power ultrafast and CW Ti:Sapphire lasers and high power, high throughput industrial applications.
Compatible Power Sensors
To verify and analyze the output power of your Millennia eV laser, we recommend the Ophir 30A-BB-18 (7Z02692) thermal power sensor and Centauri laser power meter. Additional information on this laser measurement equipment can be found on the ophiropt.com website. Other Ophir sensors and meters may also be suitable for the Millennia eV, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
