New features added to LW-10 wavelength meter

Following the launch of our LW-10 wavelength meter last May, four major improvements have been officially added to LW-10 at the beginning of 2017: a Laser Control Analog Output, a multi-channel optical switch and from the software point of view, a figure of merit and a wavelength selection range.

Figure of merit

A figure of merit has been added to the wavelength meter software interface so as to give an indication on the current running state of the laser: single mode, multimode or reduced coherence. An easy understanding of the figure of merit has been made possible thanks to a set of examples provided in the LW-10 user manual.

Wavelength selection range

A narrower wavelength measurement range can now be set in the software interface so as to reduce the wavelength range of interest. This feature helps increasing the device measurement speed, by increasing the computational speed of the software. Real time measurement speeds up to 100Hz have been reached thanks to this technic on latest computer configurations.

Laser Control Analog Ouput (PID)

A Laser Control Analog Output is now offered as an option to the LW-10. Perfect for wavelength stabilization, frequency locking, or regular deviation measurement on a single-mode laser signal, the Laser Control Analog Output provides an analog voltages output proportional to the difference between the asked reference wavelength and the wavelength measured by LW-10. It can also be used as feedback element, in a control loop feedback mechanism, i.e. PID controller.

Multi-channel optical switch

An optical switch has been added as an option to LW-10. Currently available in a 4-channel version (more channels possible on request), it makes the simultaneous measurement of several signal sources possible with the same wavelength meter and has proven to be really efficient for frequency mixing applications for instance. The optical switch has been made compatible with SpectraResolver Software so as to allow an easy tracking.
