Principle of Operation

Faraday isolators are optical components which
allow light travel in only one direction. Their mode of
operation is based on the non-linear Faraday effect

exit polarizer is also oriented at ±45°, so that the

LINOS Faraday Isolators
Isolators with a Broad
Tuning Range
Technical Overview
Introduction
The function of the tunable LINOS Faraday isolators
in the following chapter is based on a single stage
isolator. Precision mechanics allow a continuous
adjustment of the interaction between the magnetic
field and the TGG crystal without moving any optical
components.

It is possible to set the rotation angle to any value
between 0° to 45° within the wavelength range
in order to study the effects of varying degrees
of feedback. Easy access to the blocked beam is
provided by polarizing beam splitter cubes, which
divert the blocked beam by 90°.
Precision mechanics allow the exact reproduction
of adjustments previously established. And with the

A closer look
The excellent quality of the high-precision LINOS electro-optics from
Qioptiq is a testament to decades of experience at both Gsänger and
Qioptiq. The 40-year history of these products is marked by immense
customer satisfaction, and has established Qioptiq as a leader in laser
technology.
Dr. Gsänger, founder of Gsänger Optics in Munich, was instrumental in the success of
the electro-optics.

LINOS Faraday Isolators
Applications
All two stage LINOS Faraday isolators are typically
used to improve the power and frequency stability of
diode lasers used in spectroscopy, interferometry and
precision control as well as in alignment applications.
Since the output polarization and the beam position
are conserved for all two stage LINOS Faraday
isolators, the influence of the smallest feedback
effects on the laser can be quantitatively examined.

optical (Pockels) effect plays a predominant role
besides the linear magneto-optical (Faraday) and the
quadratic electro-optical (Kerr) effect. Typical electrooptic Q-switches operate in a so called λ/4 mode.

Suppression of Piezo effects
Like any other insulating material electro optical
crystals show Piezo effects when high voltage is
applied. The extent of the Piezo ringing depends
on the electro optic material and usually its effect
on the extinction ratio is negligible when used for
Q-switching. However, for pulse picking applications,
which require highly precise switching behaviour,
Qioptiq offers specially Piezo damped Pockels cells
which suppress these ringing effects efficiently.
State of Polarization
The MIQS- and CIQS-series cells are supplied with an
integrated polarizer: the alignment of the Pockels cell
relative to the polarizer thus becomes unnecessary.
The rotational position of the cell relative to the
resonator axis can be chosen at will. However, should
the polarization state of the light in the resonator be
determined by other components, such as anisotropic
amplification of the laser crystal or Brewster surfaces
of the laser rod, then the rotational position of the
