LD-PD'S VCSEL Laser Driver,With Whole aluminum housing.excellent heat dissipation performance and high strength shell. Which can make it more stable and reliable in long-term operation. 2.4 inch OLED screen and enough big to see, very clean. Low noise tunable constant current driver and TEC controller added inside. VCSEL Laser Driver foundation is developed and designed by LD-PD INC. It's easier and Convenience for customer to install pins and test. Software can also be used to control.also can add external modulated signal. We also can customization according to laser Pin definitions.

1550nm VCSEL Laser experimental measurement
1. No external modulation
(1) 1550nmTOSA Laser connecting LC-APC connector，then install laser to LD mount, connecting driver,the other end of connector FC/APC Connect with OSA.
(2) Connect USB with PC.Open driver software .set up in software，Set Max current 20mA，Set to inter (Internal modulation)mode.
(3) Set current ，Open laser
2. Add signal generator to external modulation
Set signal generator to scan mode
When set fixed-frequency to 50KHz, different voltage corresponding spectrum please see below
