Basic driver for powering laser diodes with the option to adjust maximum output current in the range of 0 - 3,5 A, and to modulate the current flowing through the diode. Maximum current value can be changed by means of an appropriate resistor. It is a solution which allows for the elimination of the capacitive-inductive effects introduced by multi-turn potentiometers.

 

Formula for the maximum current (5V on ang input):

I = 16,7 *R1/(R1+R2)

R1 should be in range of 0 - 1,5 k ohm.

 


 

Powering laser diodes:
The driver works with the following diodes: 405 nm, 445 nm, 520 nm, 638 nm, 650 nm, 808 nm, 980 nm.
By selecting an appropriate PSU and the driver in question, it is possible to power literally every laser diode up to 5W available on the market.
The examples of diodses are: 1 W 445 nm, 3,5 W 445 nm, 500 mW 635 nm, 200 mW 808 nm, 1 W 808 nm, 3 W 808 nm.
Laser diode can be soldered directly to the driver board. It has two pads on both sides of the board with the LD+ and LD - outputs.

Protection:
The driver is protected against reverse polarity and is fitted with active frequency filters which block very high frequencies (from approximately 10 MHz). The driver is also protected by a bidirectional diode (transil) which protects the system against electrostatic discharge at the input of the supply. Additionally, the driver has a softstart system that cuts off the flow of current through the laser diode at the initial phase of connecting the system to the power supply.

The MOSFET/MOSFETS must be isolated from the heatsink/plate with silicon pad as well as plastic sleeve. Short circuit between MOSFET and heatsink/plate can damage the driver and can be dangerous for the Laser Diode.

 

Modulation:
Modulation input can be used as TTL input with its logic levels of 0V and 5V or as an analog input. While using modulation voltage in the range of 0V to 5V, laser power is changing proportionally to the value of this voltage. For example 2V is around 40% power when 4V is around 80% power.

 

Powering the driver:
Supply voltage should be properly matched to the operating voltage of the laser diode and should be a few volts higher than this. For more detailed information along with calculations for the selection of power supply and heat sink, see the information section.
