STJ Series Laser Diode Drivers

1. CW Laser Diode Drivers (Intelligent Module)

The CW Laser diode driver is specially designed for various CW laser diodes at the compact size and modularization. It adopts the latest modern power electronic devices, high-speed microprocessor (MPU) program control technology, and low-power linear modulation technology (with extremely low ripple). It has excellent voltage and current output characteristics. No overshoot, no kickback, no surge and low noise in operation. It has perfect multiple protection functions, and has reliable protection for laser diode. The adjustment and control of current parameters can be selected by local and computer (set by software). In addition, the driver also has alarm signal settings. (eg. water pressure alarm, for shutdown protection). The driver adopts 16 bit "8" LED, simple menu mode display, membrane button, and has friendly user interface and fault diagnosis function. And TEC for precision maintaining the temperature on Peiltier element (TEM) is also an optional.

The CW laser diode driver is an excellent choice for laser equipment manufactures and research institute.

Benchtop Laser Controller STEM595

The STEM595 combines a laser driver and TEC controller into a compact, benchtop device with straightforward user interface. With 1.5A of drive current available, the controller can operate any Gooch and Housego 14-pin DFB laser or single mode laser.  The 3.0A of current available for the thermo-electric cooler provides ample control for typical room temperature environments. Precise temperature control results in accurate frequency control.  The STEM595 establishes a new level of low noise and linewidth performance in a benchtop device. The STEM750 and STEM650 OEM DFB modules should be considered for advanced noise and linewidth performance.

LDD2 Series OEM Laser Diode Drivers

diode driverLDD2 is a series of laser diode drivers intended for single laser diode driving as well as for laser diode arrays driving. Maximal output power ranges from 50W to 1500W, and maximal output current ranges from 5A to100A. These drivers may be used for industrial and medical applications.

Part number:     LDD2-xx-AA

The maximum output voltage is maximum output power divided by output current. Current is adjustable in range 10-100% of Imax. Imax is selected by customer. Vmax is calculated as Vmax = Power / Imax. Voltage is adjusted automatically in dependence on load, but voltage cannot exceed Vmax.

DESIGNATION

DESCRIPTION

1 (green)

Enable

Apply +5V DC on this pin to enable work of LDD.

While 0V are applied to this pin or pin is unconnected module is disabled.

Once Fault has occurred module is blocked till you eliminate fault cause, then disable module and enable it again.

2 (orange)

Fault *

If module is enabled and some trouble has occurred, module automatically stops operations and sets Fault status (Fault loop is “closed”).

In case of normal operations Fault loop is “opened”.

Maximal allowed current in Fault loop is 50mA.

3 (transparent)

Interlock

When Interlock loop is “opened” output is inhibited. You should “close” this loop to start operations (electrical resistance of “closed” loop should be below 100 Ohm level).

Once Interlock has occurred module is blocked till you “close” Interlock loop, then disable module and enable it again.

4, 9, 15 (black)

Interface Return

Return of all interface circuits.

This pin is connected to the GROUND stud.

5 (yellow)

V OUT monitor

The voltage at this pin is a monitor signal proportional to the measured value of voltage on load.

0V at PIN5 corresponds to 0V at load.

Voltage at PIN5 corresponds either to voltage at load (VMAX  < 10V) or to one-half of this voltage (VMAX  > 10V).

6 (purple)

I OUT monitor

The voltage at this pin is a monitor signal proportional to the measured value of output current.

0V at PIN6 corresponds to 0A.

10V at PIN6 corresponds to IMAX.

7 (blue)

I program

Voltage applied to this pin sets output current.

0-10V DC are linear with 0-IMAX.

8 (white)

Pulse

Apply +5V DC on this pin to allow the output.

While 0V are applied to this pin or pin is unconnected output is inhibited.
