Chapter 3 Description
The LM14S2 is a universal laser diode mount specifically designed for 14-pin butterfly laser diodes that have
integrated Thermal Electric Coolers (TECs) and Thermistor sensors. When used with Thorlabs LDC Series Laser
Controllers and TED Series TEC Controllers, a laser diode can be operated with precise temperature control for
wavelength stability and temperature tuning. A zero insertion force (ZIF) socket accepts all standard 14-pin
butterfly laser diode packages. Easy to use configuration cards allow the laser mount to be configured for all
possible laser pin assignments.
Designed primarily for Laser Diodes, the LM14S2 can also be used with many two port Electro-optic devices that
are in 14-pin butterfly packages.
A Bias-T adapter is also included allowing the laser to be directly modulated up to 500 MHz. This adapter is
intended for use only with butterfly lasers that have integrated RF modulation components (i.e. blocking inductor
and 25 Ω input impedance).
Additional safety and protection features include an on board reverse bias protection diode, remote safety
interlock connection, and the TEC Lockout circuit that prevents enabling of the laser diode unless the temperature
controller is also enabled. Designed to work with our LDC and TED controllers, the TEC Lockout can easily be
bypassed by setting a switch.
