Element™ 2
ULTRASHORT PULSED FEMTOSECOND OSCILLATORS
- Ultrashort pulses with up to MW-level peak power
- Ultra-low amplitude and phase noise
- Superior power stability
- Hands-free operation; sealed cavity for long-term operation
Element™ 2 is the newest generation of Spectra-Physics’ leading ultrafast few-cycle pulsed oscillators, specifically designed for superior stability, lowest noise, and hands-free operation. When paired with the newest version of our optional carrier envelope phase stabilization (CEP4), the result is the most stable and low-noise source of ultrashort, CEP stable pulses, opening the door to the most demanding ultrafast scientific applications.
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.
