Chapter 2 Overview and Setup
2.1 Introduction
The TLS001 T-Cube is a Fiber Coupled Laser source for stand alone operation or use
with the T-Cube Controller Hub. It uses an internally-pigtailed Fabry-Perot laser diode
that is connected to the rear panel FC feedthrough via a single mode fiber. By
connecting a fiber to fiber connection at the output, these devices deliver more useful
optical power than systems that use a receptacle with embedded optics.
This laser source is a fully functional yet highly compact controller, incorporating
driver electronics and FC/PC connected pigtailed laser diode in both 635nm and
1550nm variants. It is provided with a USB interface for easy PC control and also a
manual interface panel containing a 5 digit 7 Segment display, adjustment
potentiometer, Mode button and safety keyswitch.
The laser source operates in ‘constant optical power’ mode. The output power of the
lasr diode is monitored continuously. A feedback circuit adjusts the laser power to
achieve a constant output power.
For convenience the footprint of this unit has been kept to a minimum, measuring only
120mm x 60mm x 47mm (4.8" x 2.4" x 1.8") and with the facility to directly mount to
the optical table. The manual controls for this unit are conveniently located on the
upper surface. The Mode and Enable buttons allow the various operating modes to
be selected easily. There is also a key switch and interlock plug fitted to this compact
unit for use in laser applications requiring such functionality.

USB connectivity provides easy 'Plug and Play' PC controlled operation - multiple T-
Cube units can be connected to a single PC via standard USB hub technology, or by
using the new K-Cube Controller Hub (see over). Coupling this with the user friendly
