High-Resolution Laser Spectrum Analyzer
The model 721 is a unique instrument that operates as both a high-accuracy
wavelength meter and a high-resolution spectrum analyzer. It is for scientists
and engineers who need to know the absolute wavelength (±0.0001 nm) and
the spectral properties (2 GHz) of their CW or high-repetition-rate pulsed
lasers. Operation is available from 375 nm to 12 µm.
D2-125 Servo Controller
The D2-125 with both side and peak lock options enables high-bandwidth
( 10 MHz) servo control of lasers. Dual outputs provide feedback to both PZT
and current. The PI2D loop filter, with two-stage internal feedback, gives tight
locking to cavities and atomic/molecular transitions. Full user control over the
loop-filter parameters enables optimization for a wide variety of plants.
