Product Overview:

808nm, 5 Watt, Turn-Key System Description

Model LDX-808NM-5W is a completely integrated, turn-key laser diode source and control system for R&D and manufacturing applications. These pre-configured 5 Watt instruments give the user full control over the integrated laser module. The user can adjust drive current, optical power, temperature set-point, CW or QCW mode, and other parameters. The 808 nm laser diode is a fiber coupled module which is mounted on a Peltier cooled mounting plate inside the instrument. The laser is precisely calibrated and controlled to deliver a highly stable output.

Factory Configured Protection Settings for the Laser Diode

The LDX series instruments ship with factory configured protection settings to make sure that the laser is run safely and operates within the specified maximum operating limits. These limits include the upper current limit and upper temperature limit. Additionally, a soft-start current ramp is set to 300 milliseconds to protect the laser from thermal shock when the bias current is applied. This soft-start ramp time can be customer configured through the front panel or digital interface. These units also have clamping circuitry to protect the laser against power surges and ESD.

Peltier Based Temperature Control System

These units have an integrated TEC controller with a full P.I.D. control loop to provide fast and efficient heat removal from the laser diode source. The laser diode is mounted on a Peltier cooled mounting plate made of nickel plate copper. This internal mounting plate is machined with very high surface finish and flatness to provide low thermal resistance, typically less than 0.06 K/C. The laser mounting plate is attached to a fan cooled air duct to remove the waste heat and help keep the laser temperature stable.

Soft-Start Current Ramp

In addition to the current the temperature limit protection settings, the LDX-808NM-5W series laser source gives the user the option of setting the soft-start current ramp time from 300 milliseconds up to 10 seconds. This user adjustable current ramp allows you to customize the "power on" sequence of the source for your specific application.

User Controls

Users have full control of the fiber coupled laser module power through a touch-key front panel menu and LCD display or through the digital interface. The LDX systems can be controlled remotely by RS232 with the included LabView drivers, or by the optional USB interface.
