The LM Low Modulus coatings are used in Cascaded Cladding Light Strippers. The cascaded design includes few segments, each with a higher refractive index (e.g. 1.47 – 1.48 – 1.49).
The cascaded structure enables gradual dissipation of the cladding power, lowering hot spots temperature and increasing overall reliability. The lower modulus of the LM products is advantageous in very high power Strippers since the lower modulus reduces stress in thermal cycling.
