A response from Stefan at Thorlabs. ITC502 Benchtop Laser Diode and Temperature Controller ±200 mA / 16 W. Part Number: ITC502 -Ask a technical question Ask a technical question. The open current circuit condition is indicated by the “OPEN” indicator on the controller and a short acoustic warning. How to fix this? To ensure best possible performance, laser diodes are driven with respect to ground, offering significant advantages regarding noise, transient suppression, and stability. If the connection between current source and laser diode is interrupted, or the laser voltage exceeds the adjustable voltage protection threshold, the laser current is switched off. Is it posssible a modification to get it from (-55 Celcius to -100 Celcius). The CC mode is ideal when the lowest noise and highest response speed is required. Even when utilizing the external modulation feature, the current limit setpoint cannot be exceeded. The resolution achievable in terms of current setting for this input is the same as the resolution specified for the unit, namely 16 µA. Firmware version: 3.30. Via front panel, the resolution is limited by the display. current = 500 mA), I/O Supply Voltage (+12 V from Internal or Higher External Voltage up to +24 V), Output for Interlock and Status Indicator. I contacted you directly to provide assistance. Even in the case of power line failure, the laser current remains transient-free. Sehr geehrte Damen und Herren, Part Number: CLD1015 -Ask a technical question Ask a technical question. The menu screen allows various operation modes and options to be selected.

Part Number: ITC502 -Ask a technical question Ask a technical question. Additional 32-bit libraries install into your 'C:\Program Files (x86)\IVI Foundation\VISA\WinNT'. To answer your question about operating these in pulsed mode, we would need more information. Thorlabs offers laser diode mounts for Ø3.8 mm, Ø5.6 mm, or Ø9 mm TO can packages. Figure: Oscilloscope screenshot of a typ. They allow space-saving simultaneous current and temperature control of a laser diode with a single module. and how coudl i got the correct thermopile voltage under QCW operation? The driver should be restarted or protection mode should be switched Off-On. For optimal noise performance, choose a controller that has maximum current and voltage ratings as close as possible to, but still higher than, the required voltage and current needed to operate your laser. You can then access the functions that are summarized in the HTML manual that you will find on your PC at C:\Program Files (x86)\IVI Foundation\VISA\WinNT\TL4000\manual after having installed the drivers. The TED4015 TEC Controller is the ideal companion for the LDC4000 Series Controllers. Control range and thermal stability depend on thermistor parameters.
