4.2. Laser Installation
4.2.1. General Configuration
WARNING
Make sure the laser diode is installed correctly and the polarity switches on the
driver side are set as per the laser diode pin configuration provided by the
manufacturer. Connecting the LD driver to mount with incorrect installation will
damage the laser diode.
WARNING
Use of thermal grease is not recommended for use with the TO-can laser diode
mount. Thermal grease will creep and eventually contaminate the laser facet.
To install the laser diode, complete the following steps:
1. Unpack the laser mount. Removing the cover is optional when installing
an A, B, C, D, E, or H pin style laser. If a laser diode with a G style pin
code is being used, follow the steps in section 4.2.2.
2. Determine the laser pin configuration from the laser diode
manufacturer’s data sheets and set the LD (Laser Diode) and PD
(Photodiode) switches located on the top of the unit according to Figure
2.
