iBeam smart WS

Wavelength-Stabilized Diode Laser

Narrow linewidth (typ. 10 MHz)
High power from ultra compact diode laser, e.g. 120 mW @ 785 nm
Fully computer controlled
Perfect choice for applications like Raman, Diffuse Correlation Spectroscopy (DSC) and Interferometry

The iBeam smart WS is the ultimate choice when looking for a compact and narrow linewidth OEM diode laser system. It is the wavelength stabilized version of the iBeam smart featuring reliable wavelength-stabilized diodes. Combined with iBeam smart’s flexible, mircoprocessor based electronics it makes system integration a snap.

Options

Fiber coupling - SmartDock
Especially designed for the iBeam smart TOPTICA's SmartDock turns the iBeam smart into a rugged ﬁber coupled diode laser system. Both single-mode and polarization-maintaining fibers can be connected to the SmartDock. Better than 60 % coupling efficiency is guaranteed but efficiencies up to 90 % have been demonstrated due to the high beam quality of the iBeam smart.
Applications
- Raman microscopy
- Raman spectroscopy
- Diffuse Correlation Spectroscopy (DSC)
- Linewidth sensitive applications using acousto-optic-deflector
