Laser Diode Drivers
  Laser Diode Driver For Laser Diode Products and Devices
Apollo Instruments' laser diode drivers operate in either CW or QCW mode with up to 100A of output current. The rack-mountable drivers can be controlled locally from the device's front panel or remotely through the standard RS-232 interface. Proven protection features are installed to safeguard laser diodes. Pulse applications can be triggered externally with an external modulation input port or with the system's internal function generator; both are capable of achieving minimum pulse widths of 100μs with several waveforms and a wide range of frequencies. With the different compliance voltage (such as D560's 5V, D1060 's 10V, and
D3660's 36V), you are capable of operating different high power laser diode devices with the ease and reliability of Apollo Instruments' drivers.

In addition to our standard designs, Apollo Instruments offers many existing design modifications that allow for a high degree of product customization. Apollo Instruments also supplies a variety of optical options, such as low aberration focusing and/or collimation assemblies, mirrors, filters, spatial filters, and other accessories. Please inquire for further information if these options or other features can better help us meet your needs.
Short Pulse Width
This is an internal short pulse option. Standard pulse width is limited to 30ms. This option allows for a pulse width as narrow as 100µs. An input signal is not necessary to utilize this function. It is fully internal and can be set by using the functions on the LCD screen.


Analog Modulation Input
An external analog input can be used to control the output of the laser diode driver. The magnitude of the analog signal controls the current, and the frequency of the analog signal controls the pulse frequency. The laser diode driver is capable of following an input signal with a minimum pulse of 100µs and a maximum pulse frequency of 1kHz. The external analog signal input is the modulation input BNC connector on the back panel.


Digital Modulation Input
An external digital input can be used to control the output of the laser diode driver.  The laser system output is capable of following an input signal with a minimum pulse width of 100µs and a maximum pulse frequency of 1kHz. The external digital signal is delivered to the digital modulation input BNC connector on the back panel.


Foot Pedal Switch
The foot pedal switch adds another convenient way to control the operation of the laser diode driver. The foot pedal ensures that there is no laser output until it is pressed. 


TEC Driver
TEC driver can be included in the laser driver. The microprocessor-controlled TEC driver provides dynamic control of the TEC cooling stage, allowing minimized temperature variation.
