A laser mirror is a high-precision optical component engineered specifically to withstand and manipulate laser light. It is a critical element in any laser system, whose design and performance directly determine the laser's output characteristics, beam quality, and the overall success of the system. Compared to standard mirrors, it must meet exceptionally stringent requirements for reflectance, laser-induced damage threshold, thermal stability, and surface figure accuracy.
High reflectance and high laser-induced damage threshold.
Low absorption and scatter.
Excellent thermal stability.
