Laser Components is offering a range of pulsed laser modules and high-voltage supplies. The latter are suitable for use in the operation of discrete avalanche photodiodes (APDs) and APDs with integrated temperature sensors.

With the ABC (analogue bias controller) and DBC (digital bias controller) series high-voltage modules, the output voltage can be in the range of ±120V up to ±550V and can be adjusted in a precise manner. By setting the temperature coefficient of the module to that of the APD, the internal temperature-gain compensation feature ensures accurate control that is free from temperature drifting.

In the ABC series, the output voltage is adjusted using either a simple potentiometer or a control voltage. In the DBC series, digital control is also possible. An RS232 or SPI interface can be used for this purpose. In both modules, an additional control voltage makes it possible to either regulate the amplification of the APDs in a closed control circuit or modulate it directly.

The LS series standard pulsed laser modules and LC series customised pulsed laser modules are as small as a matchbox. The 905nm and 1,550nm modules are available with parameters that are either fixed (LC series) or variable (LS series) in their adjustability.
