Pulsed Wavemeter® Wavelength Meter - ATlaser di Andrea Tappi

Pulsed Wavemeter® Wavelength Meter

Pulsed Wavemeter: provides the highest accuracy wavelength measurement of pulsed lasers or OPOs.

These systems determine the absolute wavelength of a test laser by using static Fizeau and Fabry-Perot etalons to generate spatial interference patterns that are compared to the patterns generated with a built-in HeNe laser wavelength standard. The WA-4550 Pulsed Wavemeter provides the highest accuracy measurement of ± 0.02 cm^-1 over the wavelength range of 400 to 1100 nm.

The main features are:

Pulsed and CW laser wavelength measurement
Absolute wavelength accuracy of ±0.02 cm^-1 (WA-4550)
Built-in HeNe laser wavelength standard for continuous calibration
Operation from 400 to 1100nm with the WA-4550
Displays wavelength (nm) or wavenumber (cm^-1)
Visible tracer beam to facilitate alignment
Asynchronous operation with automatic pulse detection
Measures spectral characteristics of stored spectra
USB, RS-232 and IEEE-488 interface capability
