- Laser Diode Mount for 14-Pin Butterfly Packages
- Zero Insertion Force (ZIF) Mounting Socket
- Type 1, Type 2, Type 2 with Bias-T, and User-Defined Pinout Configurations
- LED Indicates When Laser is Enabled
The LM14S2 Universal 14-Pin Butterfly Laser Diode Mount is designed for use with lasers and two-port electrooptic devices in a 14-pin butterfly package. The top surface has heat sink fins and a recessed region to mount the laser diode, resulting in a low profile package with a temperature coefficient of 3 °C/W. The LM14S2 also includes a laser diode TEC lockout featurea that disables the laser when the TEC controller is not active. The LM14S2 supports maximum laser and TEC currents of 5 A each. In order to utilize the TEC controller, the laser must have an integrated thermoelectric cooler (TEC) or thermistor sensors. This mount also features a zero insertion force (ZIF) socket, a remote safety interlock connection, and an LED to indicate that the laser diode is enabled.
The LM14S2 eliminates the restriction of fixed-pin configuration mounts by using exchangeable configuration cards that plug into a connector located on the bottom of the mount. Two cards are delivered with the LM14S2. One card provides compatibility with both Type 1 Pump Laser Diodes and Type 2 Telecom Laser Diodes. For the pin diagrams that correspond to these types, please refer to the Pin Diagrams tab. The second card is a user-configurable card (LM14S2-UA) designed to allow custom wiring of the mount. Additional user-configurable cards are available and can be ordered separately. Please note that even with an LM14S2-UA, only anode-grounded diodes can be used with the LM14S2 butterfly laser mount. However, due to limitations in heat sinking, it cannot be used with our tapered amplifiers.
In addition to the configurable pinout feature, a bias-T adapter is included, allowing for RF modulation of butterfly lasers specifically designed with this capability. It features a female SMA connector for an RF source up to 500 MHz, and is designed for lasers with a type 2 pin configuration including an internal bias-T and built-in blocking inductor. For more details on the pin assignments, please refer to the Pin Diagrams tab as well as the spec sheet for the specific laser diode to be used. Please note that Thorlabs' butterfly package laser diodes are not compatible with the bias-T adapter.
The LM14S2 is pin-for-pin compatible with all Thorlabs' benchtop laser diode and TEC controllers, and most of our platform laser and TEC controllers as well, eliminating the need for custom-made interface cables. Thorlabs also manufactures customized, application-specific butterfly mounts for OEM customers. Please see the OEM Modules tab for details.
