Compact Laser Diode Driver For Laser Diodes with TEC and Current Driver

PD-LD’s compact Laser Diode Driver is a compact all-in-one unit designed for convenience of use, and combines a user interchangeable mount for a laser diode, SLED, SOA or similar device, a current driver and a TEC controller, all in a self-contained enclosure.This product includes a USB port and a software control application with a graphical user interface (GUI) for real-time device monitoring, control and data logging.

This Driver is used with either a 14-pin butterfly mount (provided with Type I, Type II and custom pin out routing boards) and/or a DIL mount. The mounts are user-interchangeable and are sold separately from the base unit.

Note:* The modulation signal peak level is determined by the max driving current of the laser diode,It may Permanent damaged the LASER DIODE When Customer over Modulated.Before Appling the Modulated Voltage into this Drvider.Please make sure the peak Voltage level of the driver suites for the LD’s Safe driving Current. 


The following we give out two Operation Conditions

1. The laser modulation signal is only the external modulation input signal, External modulated signal’s Input Voltage is limited by the max Driving Current( ILim),The max peak voltage level Vmax should less than 5×ILim(A),and the lowest voltage should>0V, one negative voltage is prohibited.

eg:One DFB LASER DIODE’s max driving Current is 0.15A, External modulated signal’s peak Voltage level should be: Vmax≤5×0.15=0.75V,The lowest modulated peak voltage should be:Vmin≥0V;


2.When the laser modulated signal is selected as the synthesis with external signal and internal sawtooth.When the maximum current of the internal sawtooth wave is set at Imax, the minimum current is set at Imin, the maximum Volatge level Vmax of the external modulation signal should be less than 5 x (ILim-Imax) (A), and the minimum level Vmin of the external modulated signal should be greater than - (Imin /5).

Example: the maximum safe drive current of the laser, 0.15A,

The maximum current of the internal sawtooth wave is Imax=0.075A,

The minimum current Imin=0.015A,

The external modulation signal peak level Vmax is less than 5 x (0.15-0.075) =0.375V.

The minimum level Vmin is (0.015)÷(5) =-0.003V;
