Features

Ultrashort Pulses with Highest Stability

With its robust design, the Element 2 oscillator family provides outstanding power stability and superior carrier envelope offset beat note power and frequency stability. With the various Element 2 models Spectra-Physics offers shortest pulses of sub-7 fs with an average power of >500 mW, and sub-10 fs pulses with an average power up to >1000 mW. The Element 2 ultrafast oscillator is pumped with an integrated Spectra-Physics® Millennia® eV™ solid state green laser. The resonator is based on Dispersive Mirror (DM) technology for precise intra-cavity dispersion management and optimum stability for mode-locking. Therefore, Element 2 guarantees highest quality, outstanding peak power, and ultrafast pulses with extraordinary spectro-temporal characteristics even for the most demanding applications.

Compatible Power Sensors

To verify and analyze the output power of your Element 2 laser, we recommend the Ophir 3A-PF-12 (7Z02720) 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 Element 2, depending on application. Ophir also works with laser system developers to achieve embedded beam diagnostics to monitor system performance as an OEM solution.
