THORLABS TCLDM3 Operating Manual

Temperature-Controlled Laser Diode Mount for TO-3 Lasers
Description:
The TCLMD3 is a temperature-controlled laser diode mount. When used with Thorlabs LDC500 Laser Controller and
TEC2000 TEC Controller, a laser diode can be operated with precise temperature control for wavelength stability and
temperature tuning. An eight pin socket accepts standard TO-3 laser packages. Easy to use internal switches and
jumpers allow the laser mount to be configured for various laser configurations. The 8 pin socket conforms with the
most popular TO-3 lasers (e.g. SDL and others).
The TCLMD3 was designed with features that allow it to be easily incorporated into complex systems. The front of
the TCLMD3 has a 1.035"-40 thread to accept a wide variety of Thorlabs SM1 1" optics mounts and accessories.
Also standard with the mount are a 4-40 tapped holes on 30mm centers for mounting any number of Thorlabs cage
assembly products.
A 50Ω RF input using a bias-tee allows the laser to be directly modulated up to 1GHz.
The TCLMD3 uses two thermo-electric coolers (TEC) to precisely regulate the operating temperature of a laser
diode. Each TEC element is capable of up to 13W of cooling at a maximum operating current of 5.6 amps. The two
TECs are connected in series so that a single connection provides up to 26W of cooling. Temperature sensing is
done by one of two ways. An AD590 Temperature Transducer provides a linear temperature monitor proportional to
the laser temperature in degrees Celsius. A 10kΩ NTC thermistor is also provided for controllers that only work with
thermistor feedback. The Thorlabs TEC2000 supports both sensors.
The internal TECs and temperature sensor may be bypassed for TO-3 lasers that include these features. All laser
pins are available on the 9-pin DB9 connector.
