Ophir Optronics Ltd. has announced that the CO2 Laser Optics Div. of its Optics Group has developed an MMR-P intracavity mirror coating for use in high-power CO2 laser systems based on multimirror-cavity optics. The company says that the coating maximizes reflection (>99.90% for S-Pol), improves performance, protects highly sensitive mirror surfaces and prolongs product life. The OEM-approved coating provides good P reflection (>99.80%) and total random reflection (>99.85%) and is suitable for Cu and Si mirrors. It is ultraviolet-resistant and allows for a phase-shift tolerance of ±2 at 45° and >70% reflection for 630 to 670 nm, for good cutting and cleaning capabilities. It can be used as a total reflector or as a zero-phase-shift total reflector and can be applied to a level-changing mirror in two-tiered resonator systems.
