Naming scheme of the LDH Series laser heads

Description:

"C": Laser head with thermoelectric cooler, mandatory for some laser heads, optional for all other laser heads.

"F": Laser head emits a divergent beam from FC/APC fiber output connector

"M": Transversal multi mode structure, reduced coupling efficiency into single mode fibers
