Er:YAG Laser-2940nm-Laser Mirror

Our reflector is an optical product with good comprehensive performance. When applied to the laser resonator, the laser mirror must meet the requirements of low reflection loss, good transmission in a certain wavelength range, high optical quality of the surface, and good anti-high light intensity, that is, high damage threshold, to avoid laser-induced damage. Our laser mirror substrates are high-quality fused silicon/sapphire designed for high-power laser sources. These mirrors have high reflectivity >99.8%, high damage threshold, and wavefront distortion > λ/4 is an ideal choice for laser applications in cavities.

Er:YAG Laser-2940nm-Output Mirror

Our output coupling mirror is a semi-transparent medium mirror for the laser resonator, which can partially reflect laser to the resonator for gain amplification and partially transmit and output stabilized laser. The constant reflectivity/transmittance ratio (R/T) of the laser output coupling mirror is the main property of the partial mirror in the resonator. The pump power threshold, maximum output power, and output efficiency of the laser are highly dependent on the R/T value of the output coupling mirror. Our output coupling mirrors have a reflectivity of 70%~99.5%. They are made of sapphire/Neodymium-doped yttrium aluminum garnet (YAG) to transmit high-power laser …

Er:YAG Laser-2940nm-Turning Mirror

Our turning mirrors use high-quality substrate materials, including sapphire and Corning 7980 substrates, and use high-reflection (HR) coating technology to provide extremely high reflection efficiency in the operating wavelength range of 355 nm~2940 nm. Precision Processing effectively reduces light scattering. Within a certain incident angle range, the reflectivity of the HR film layer to natural light or S-polarized light and P-polarized light can be as high as 99.9% or even close to 100%. It has excellent performance and can be applied to various high-precision lasers.
