Product Overview:

808nm, 100 Watt, Turn-Key Laser Diode Source System Overview

The model LDX-808NM-100W source and control systems are high performance, pre-configured laser diode systems designed for R&D lab and manufacturing applications. An integrated 100 Watt, 808 nm DILAS fiber coupled source is precisely controlled to provide a high stability output.

The LDX-808NM-100W systems include a Coherent Laser, Inc. (formerly DILAS) high power fiber coupled source, a precision high power laser diode current source, a 336 watt Peltier - TEC temperature controller and a water cooled base laser mounting plate. All of these components are integrated into a 3U high, 19 inch wide rack-mount enclosure.

Protection Features Optimized for High Power Laser Diodes:
These source and control systems are built with protection features designed specifically for high power lasers. They are pre-configured with a 300 millisecond soft-start current ramp from 0 to the desired laser output power set point. Additionally, the user can set any ramp time period from 300 msec up to 10 seconds. These protection circuits are optimized for lasers with optical output power levels from 50 Watts to 300 Watts. Other protection features include a factory set upper temperature limit and a maximum current and voltage limit. All limits are set to the DILAS safe operating rang specifications. The LDX series systems have integrated AC power surge clamp circuits to prevent any possible damage from short power brown-outs or black-outs, as well as any potential for ESD surges. They also have an open circuit detector and redundant temperature sensors to protect the laser from thermal damage.

Flexible User Controls:
Users have full control of the DILAS laser through a touch-key front panel menu and LCD display or through the rear-panel digital interface. Laser output power can be adjusted in the optical domain (W) if the user chooses the automatic power (APC) control mode, or by adjusting the current level (ACC mode). The user also has control over the laser temperature set-point within the safe operating range. The LDX system can be controlled remotely by RS232 or by USB. They ship with LabView drivers. Sequencing software is also available for pre-programming multi-step tests.

QCW, Modulation, Internal Function Generator:
In addition to CW mode, the LDX series offer QCW and modulation modes. The control unit ships with an internal function generator which can be used to set the quasi-CW pulses. Also, the user can use an external source to trigger QCW pulses. The control unit will accept either TTL or analog modulation.

Primary Applications:
The high power 100W LDX model systems are used in plastic welding, soldering, illumination, selective laser melting, heat treatment, medical and many materials processing applications.
