1500mA, 28W Controller System for Eagleyard Photonics Non-Fiber Butterfly Lasers

Product Overview:

1500mA, 28W Controller System for Eagleyard Photonics Non-Fiber Butterfly Laser Diodes

These pre-configured control systems are designed and configured for controlling Eagleyard Photonics single mode laser diodes.

The system includes: a precision current source, a full PID temperature controller, an actively cooled heat sink, and all of the required connecting cables. The current source offers industry leading protection for your laser diode. The mounting socket and heat sink offer a high performance, pre-configured mounting solution for a butterfly package. This system is an affordable, high performance solution for safely powering your laser and running at a stable temperature in laboratory environments.

Laser Diode Protection Features

These units offer the highest level laser diode protection available to ensure that your device under test is protected at all times. Soft-start current, current and temperature limits, and a fast shut-down sequence keep your device protected at all times. Additionally, transient filters and AC line filters protect the laser against brown-out or black-out power conditions. The precision TEC controller offers a full P.I.D. control loop for fast and efficient thermal stabilization.

A back-panel safety interlock connector ensures that the laser diode current is not switched on until the user has determined it is safe to do so.

Temperature Controller Features

The full PID loop provides millidegree temperature stability, and can quickly stabilize high heat loads to the temperature set-point to reduce the risk of damage to your laser.

User adjustable upper and lower temperature limits can be programmed to protect the laser diode and the Peltier device. Additionally, TEC output current limits are user-configured to protect the Peltier device from over-drive damage.

Modulation, Internal Function Generator, and QCW Pulse Modes

In addition to CW (continuous wave) mode of operation, the laser diode controller offers flexible modulation capabilities and a QCW mode. The rear panel of the controller has a BNC input for an analog or TTL digital modulation input with a 10k Ω input impedance. The controller has an internal function generator which can be used to set the quasi-CW pulses. In QCW mode, the user can also set the 100μs to CW pulses from a remote TTL signal source.

Intuitive Front Panel User Interface

The user also complete control of all laser diode bias and temperature control parameters through an intuitive front panel menu. The front panel has an LCD display with a key pad. For remote control, these systems come with a standard RS-232 interface and can be ordered with an optional USB interface. The LabView GUI (included) makes set-up and control of the system fast and simple.
