If your application requires the higher voltages typically necessary for driving blue and other short laser diodes, consider our LDC202C, LDC205C, or LDC210C controller. The laser diode controller can then be used to increase DC voltage to the proper level. The LDM9T is not compatible with any style F connections, even though the configuration is very similar to the D style configuration. Since the input and output beams from the Anamorphic Prism Pair are offset from each other, prisms should be mounted on another cage or lens tube axis. Many of our mounts include a TEC that supports temperature regulation of the housed laser diode, indicated by the thermometer symbol on the links below. 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. 1 peltier positive (top plate will cool down) The CAB diagram shows one, but the HLD doesn't. These laser diodes only contain a laser diode and ground pin, as shown to the right in figure 1. Solving the first equation again with your actual focal length and major axis divergence angle yields the actual major axis beam diameter, = 3.3 mm. Full details of the assembly and operation of the LDM56F Mount can be found in the LDM56F operating manual. In these configurations, the laser diode houses a monitor photodiode tied to either the cathode or anode ground of the laser diode. Stable and clean RF sources should be used to avoid overdriving the laser diode. The SM1 threading of the adapter can then be used to attach the lens/mount/adapter to the laser diode mount's front plate. The LM14S2 also includes a laser diode TEC lockout feature a that disables the laser when the TEC controller is not active. In order to properly modulate the laser diode emission, the correct modulation voltage must first be determined. It can then be mounted in the SM1A6T SM1-to-SM05 adapter. There are four pin configurations (A, B, C, and D), which are completely compatible with the LDM9T mount. The CLD1015 Laser Diode and Temperature Controller is a complete driver package designed to drive and cool pigtailed butterfly laser diodes (see the Pin Diagram tab for details). The focal length of the lens needed to collimate a 30o diverging beam into a Ø3 mm collimated beam is = 5.6 mm. Lasers / Coherent Sources Thorlabs provides an extensive selection of lasers and other specialized coherent sources, such as our correlated photon-pair source. The capacity of the mount is 6.3 Watts, as opposed to the TCLDM9 which has a 20 W capacity. The HL6548FG 660 nm, 90 mW laser diode features a style F configuration. Mounted and unmounted aspheric lenses with focal lengths greater than 8 mm can be cage mounted using our 30 mm cage system. Thorlabs' optoelectronics mounts include mounts for various laser diode packages including Ø5.6 mm, Ø9 mm, and 14 pin butterfly, including diodes with fiber pigtails. The LDM9T Laser Diode Mount has a standard 4-pin LD and PD mounting configuration. Unmounted aspheres can be epoxied to an LMRAxx adapter, which can then be mounted in an SM1A6T SM1-to-SM05 adapter. Thorlabs specializes in the building blocks for laser and fiber optic systems. The compact housing protects the pigtail from physical damage, while also offering excellent thermal characteristics. Otherwise it is floating. Care should be taken to note the orientation of the laser diode emission. If a third-party controller is used, see the laser diode connector pin configuration in the operating manual to determine the proper connections. Options are available that enable integration into a lens tube or cage system. SM1 (1.035"-40) Thread and 30 mm Cage System Compatible The LDM9T is a laser diode mount including an integrated thermo-electric cooler (TEC) and temperature controller to precisely regulate the operating temperature of a laser diode. Figure 3 shows an anamorphic prism pair magnifying an elliptical beam minor axis to produce the desired symmetric beam.
