Diode Laser Driver (Laser Diode Driver, Diode Driver)
 
The laser diode driver LDD-AAVV-T is a high current-constant laser diode driver with a thermo-electric cooler controller. Current control, transient suppression, over-temperature protection, short circuit protection, and over current limit are provided. A temperature sensor is used to measure the temperature of the laser diode and then the constant-temperature is kept by automatically adjusting the current of the thermo-electric cooler.

LDD Series CW OEM Laser Diode Drivers
 

The LDD series is a new family of OEM laser diode drivers designed for the emerging high power laser diode industry. The LDD series is ideal for high power applications where economy is important and performance cannot be compromised.

 

Compact size is possible due to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics.  The LDD is virtually wire free.

 

Power factor is greater than 0.99 and conducted emissions meet stringent European regulations. No additional line filter is required to meet EN 55011 emission requirements.

 

The LDD family has been designed with the knowledge that a high power laser diode is an expensive device. Rise and fall times are strictly controlled to reduce high voltage transients which could damage the laser diode.

Pin Name

Functional Voltage Level

Description

1

Enable (input)

High=RUN=+5V to +15V Low = OFF = 0V

The Enable function turns the output section of the power supply ON and OFF. When the power supply is enabled, current is delivered to load as programmed via Iprogram(+), Pin 7. Rise times resulting from Enable are approximately 25msec.

3

Interlock (input)

Open = OFF Connect to GND = RUN

The Interlock function can be connected to exter-nal interlock switches such as door or overtemp switches.

4

GND

 

Interface return.

5

*Vout Monitor: (output)

0-10V = 0-Voutmax

The output voltage of the supply can be monitored by Vout Monitor. See note below

6

Iout Monitor (output)

0-10V = 0-Ioutmax

The output current of the supply can be monitored by Iout Monitor.

7

Iprogram(+): (input)

0-10V = 0-Ioutmax

The power supply output current is set by applying a 0-10V analog signal to Iprogram(+).

8

Pulse Control (input)

(LDD-3000 only)

TTL High = On

TTL Low = OFF

Default = On (LDD-3000 only)

The output of the LDD-3000 may be pulsed by applying a TTL signal to Pulse Control, pin 8. The amplitude of the output current pulse is deter-mined by the current level programmed via Pin 7, Iprogram(+). Rise fall times of <1msec are typical. Contact Lumina Power for faster rise and fall times. If left unconnected, the default will be ON for CW operation.

GND

* If maximum compliance voltage is less than 10V, Vout Monitor will read output voltage directly. If maximum compliance voltage is greater than 10V, then Vout Monitor will be scaled such that 0-10V = 0-Voutmax.
