Laser TEC and Current Driver Mount
Precise control of the temperature and current for the DFB laser is required in order to achieve high-precision spectrum applications. KONGTUM developed a high-performance laser controller integrated TEC driver, low-noise current driver and a 14pin Butterfly Laser mount. For other packaging like TO-can, KONGTUM also has TO laser mount. The Driver Mount also has a USB com port, can be monitored and controled through the PC software.

Note: * The modulation signal voltage range is determined by the operating current of the laser diode. The LASER DIODE may be permanently damaged if the current is modulated over the Max Operating Current. Before the modulated signal was inputted, please make sure the signal peak voltage is below the laser diode Max Operating Current.
1. Internal modulation signal
When using the internal modulation signal, please refer to laser parameters, set the appropriate current maximum value on the PC software to limit the modulation current in a safe range.
2. External modulation signal input
When using the external modulation signal input, should refer to the maximum allowable operating current Imax of the laser. The peak value of the modulation signal voltage should be below Imax/(0.1A/V). For example, the maximum operating current of the laser is Imax=0.15A, then the peak modulation signal should be less than 0.15/0.1=1.5V. The current limit value is also setted on the PC software.
