The laser wavelength meter measures the wavelength of both CW and pulsed lasers of any repetition rate. The wavelength can be displayed in GHz wavenumbers or nanometers with vacuum and air readings available.

Product Introduction

The laser wavelength meter measures the wavelength of both CW and pulsed lasers of any repetition rate. The wavelength can be displayed in GHz, wavenumbers, or nanometers, with vacuum and air readings available. The meter will read the peak wavelength of sources as wide as 2nm from 380nm to 1095nm. Bandwidths wider than 2nm can be accommodated at the longer wavelengths.

The meter is easy to use. Just turn on the readout and get the beam within 10 degrees of normal incidence to the sampling probe. The probe has a 2-meter fiber optic cable and takes up a minimum of beam path space. Most intensity variances are automatically accommodated, but for the strongest and weakest signals a front panel attenuator adjustment and intensity readout quickly afford accurate readings. No special triggering modes or setups are required for pulse capture.

The meter is portable with AC and battery power. The large easy-to-read display is backlit and has adjustable contrast control for easy viewing. Configuration settings are maintained in memory and retrieved on start-up for convenience. Communication with the meter is also easy with built-in RS-232 and an optional GPIB interface.

The meter is easy to read with front panel adjustments of contrast and back-lightning for the extra-large display. Parameters that have been set-up are clearly displayed in addition to signal intensity and pulse retrieved indicators. When in the CW mode of operation the display is updated at an easy to read 3Hz rate. While in the pulse mode the display is updated at 3Hz and maintained for 15 seconds after a pulse for reading single events.

Calibration is maintained by sophisticated algorithms that monitor the meter’s response. Periodically and upon indication from the algorithms the meter is referenced to the fundamental Ne lines.
