Interference Filter

Interference filter with a small line with (FWHM 0.4) and a transmission from over 90 % for different Wavelength. The specified wavelength refers to a angel of 6°. By rotation of the Interference Filter is a tuning range from 20 nm possible. 

Available Filters on stock :

  • 780 nm (tuning range app. 783-761nm)
  • 798 nm (tuning range app. 801-783nm)
  • 817 nm (tuning range app. 820-802nm)
  • 852 nm (tuning range app. 855-834nm)

Diode Laser with Amplifier

Our new NarrowDiode Laser is a small sized and low prices external cavity Diode Laser. The wavelength separation is realized by a low loss interference filter instead of the common diffraction grating.

Due to this new design, the Laser is characterized by a very high robustness against mechanical and thermal disturbances. Another advantage of our Laser is the fixed output beam, that leads to a very high stability, because the direction and position of the output beam are almost independent from the wavelength.

Furthermore, the Laser guarantees a very small bandwidth and a very large tunability at the same time, it also can be wavelength stabilized by frequency modulation spectroscopy.

With the new amplifier output energies up to 1,5W are reachable.

NarrowSHG

Our new NarrowSHG is a stand-alone second harmonic generator for frequency doubling of single frequency lasers such as Ti:Sa lasers, dye lasers and diode lasers.

The unit contains mode matching optics for the external laser and beam shaping optics for the frequency doubled light. The compact resonator with a high mechanical and thermal stability includes digital locking electronics with automatic relocking Hänsch-Couillaud or Pound-Dever-Hall stabilization.
