These fully integrated high power systems include a highly reliable fiber coupled diode laser module with a fully configured control system. The control system is a precision current source, a high power 336 watt Peltier – TEC temperature controller and a water cooled base plate to remove heat from the laser. All of these components are integrated into a 3U high, 19 inch wide rack-mount enclosure.
These instruments can be rack-mounted or used on a laboratory bench. The robust control unit is capable of dissipating up to 500 watts of heat by utilizing a water cooled base plate combined with high power TEC elements.
Factory Pre-Set Limits and Protection Features
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; the user can set the ramp time period from 300 msec up to 10 seconds.
The built-in laser protection circuits are optimized for lasers with optical output power levels from 50 Watts to 300 Watts. Protection features include a factory set upper temperature limit and a maximum current and voltage limit. All limits are factory set to safe operating range 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 fiber coupled diode 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 the optional USB interface. They ship with LabView drivers, and sequencing software is 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.
