These Laser Diode Controllers are ideally suited to powering the
expanded selection of Vertilas VCSEL diodes presented on page
460 and 461. The Vertilas VCSEL diodes can be plugged directly
into the onboard sockets. Any other VCSEL diodes with
grounded laser anode can be operated using a shielded DB9 cable.
These controllers are designed to supply the low drive current
typical of a VCSEL. Special attention has been paid to ensuring
an extremely clean low noise drive current to prevent damage to
highly sensitive VCSEL Diodes.

An integrated current modulation feature allows high speed sweeping of the wavelength of the VCSEL for spectroscopy
applications. Alternatively, an analog input enables external modulation of the wavelength. An adjustable upper limit on the
modulation current protects the laser diode from accidental damage when using either of these features.
A temperature window indicator LED shows when the diode leaves a desired operation temperature range, thus providing
an indication that an unwanted wavelength-shift may have occurred (VITC002 only). Two other features, an open circuit
detector, and an interlock both enhance the safe operation of a sensitive VCSEL diode.
