Product information "Excelsior® One™ CW Lasers"

One Box; 375-1064 nm; Average Output Power 20-500 mW; Power Stability <±1.0%, <±2%; Spectral Linewidth <0.01 pm -<1.5 nm; Noise <0.2%-<1% rms

MKS Spectra-Physics’ Excelsior™ One™ series of UV, visible (VIS) and near IR (NIR) CW lasers are based on MKS Spectra-Physics’ “It’s in the Box™“ design with the laser head and controller combined in a single, compact package. The Excelsior One series is available as free-space and fiber-coupled lasers that include fourteen different wavelengths from 375 to 1064 nm and delivers up to 500 mW of average power.

The Excelsior One series includes both direct diode and diode-pumped solid state (DPSS) laser technology in a compact package offering multi-mode and single frequency options using the exact same mechanical footprint.

The Excelsior One series offers 1064 nm in the infrared, while the visible wavelengths options at 473, 515, 532, 542, 553, 561 and 594 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.

The Excelsior One series is also offered with fiber-coupled options from 405 to 1064 nm using single mode (SM), polarization maintaining (PM) 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.
