Features

One Platform for 12 Wavelengths

The Excelsior One series offers 1064 nm in the infrared, while the visible wavelengths options at 473, 515, 532, 542, and 561 nm are based on patented frequency doubling techniques for the DPSS models. Direct diode models – with the option of high speed modulation and serial software interface – are available at 375, 405, 445, 488, 642, and 785 nm. For ease-of-use and laser power control, all Excelsior One lasers are equipped with an RS 232 software interface.

The Excelsior One lasers are ideal for customers who rely on modularity in their instrument design. With the Excelsior One series, customers can choose among over 50 different versions in a single footprint and a single supply voltage. This enables maximum independence and the fewest design constraints.

Fiber-Coupled Versions

The Excelsior One series is also offered with fiber-coupled options from 405 nm to 1064 nm using single mode, polarization maintaining fibers. These fiber-coupled lasers offer outstanding power stability in harsh operating environments, and a polarization extinction ratio (PER) of less than -30 db over the specified operating temperature range. The fiber-coupled Excelsior One lasers are terminated with a FC/APC connector.

Compatible Power Sensors

To verify and analyze the output power of your Excelsior One laser, we recommend the Ophir PD300-UV (7Z02413) or PD300 (7Z02410) 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 Excelsior One, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
