Product Details

Pulsed Diode Laser – DL nSec

 

Diode Laser with Sub Nanosecond Modulation

The DL nSec is a compact diode laser with sub nanosecond digital modulation. It enables arbitrary digital modulation and on-demand triggered pico second pulses in a common operation mode. It provides pulse widths of ~300 ps FWHM (specifications depend on the wavelength and diode type). A unique feature of DL nSec is its 100% extinction ratio. The laser offers convenient control via a USB interface.
