Page 4: Part 2. Description
• Clamshell Design Eliminates Thermal Gradients Across Diode • Bias-T Adapter for RF Modulation of Laser Current >1 GHz Thorlabs' LM9LP is an LD and TEC mount designed for use with all of our 3- and 4-pin pigtailed diodes . The compact housing protects the pigtail from physical damage, while also offering excellent thermal characteristics. -
Page 5: Part 3. Setup
• Determine the laser pin configuration from the laser diode manufacturer’s data sheets and set the LD (Laser Diode) and PD (Photodiode) switches on the side of the LM9LP according to the diagram and picture below. Case Case... - Page 6 The other laser and photodiode pin will be isolated from the case. The LM9LP was designed to operate the laser case at ground potential therefore this common pin will be inserted into either of the holes marked ‘G’...
