Laser diodes are typically oriented parallel to the notch; however there are many exceptions, especially for different laser diode packages. The specifications for the L785P25 laser diode indicate that the typical perpendicular and parallel beam divergences are 30o and 8o, respectively. Next, check to see if the numerical aperture (NA) of the diode is smaller than the NA of the lenses so that the light emitted from the laser diode is not clipped by the lens: Figure 3. Designed to work with our LDC controllers the TEC Lockout can easily be bypassed by setting an on-board jumper. Style F laser diodes are incompatible with the LDM9T mount. To calculate the focal length needed to achieve a Ø3 mm collimated beam diameter, we can use: where is the focal length that produces the desired perpendicular beam diameter, . The electrical connections for these diodes vary based on the internal circuitry of the diode. These laser diodes also feature a monitor photodiode; however, the pin layout prohibits the mount from powering the laser diode and photodiode simultaneously. Andrew, Laser Diode Mount With Thermoelectric Cooling. The TEC element contained in this mount can sink up to 3 A to keep the laser diode at a constant temperature. Inserting a TO can into most sockets is fairly easy; this mount has the worst socket I have ever used. Unmounted prisms may be used as well. Again, adjustment of the aspheric lens can be made at the LMRA5 and SM1A6T adapters. Grounding the photodiode pin will allow the mount to drive a laser diode only (no photodiode) configuration with the LD pins at the 3 o'clock and 9 o'clock positions. A fifth configuration, Style E, may be directly compatible with the mount or may require modification to the mount depending on the orientation of the laser diode pins. With this configuration, it is not possible to apply the correct voltage bias across both diodes simultaneously using the LDM9T laser diode mount. Care should be taken to note the orientation of the laser diode emission. Maximum difference in temperature achievable between the hot and cold faces of the TEC.
