TECHSPEC® Nd:YAG Laser Output Couplers are partially reflective mirrors used in laser cavities to transmit a portion of the resonating intracavity beam. The first surface of these output couplers is coated with a partially reflective mirror coating while the back surface is coated with an anti-reflection coating at the laser wavelength to prevent reflection losses. In addition to being used as output couplers, these optics can also be used as partial reflectors for beam attenuation or as general beamsplitters. TECHSPEC Nd:YAG Laser Output Couplers are manufactured from UV fused silica substrates to provide excellent thermal properties and feature laser grade surface specifications. Laser Output Couplers are available with design wavelengths of 532nm or 1064nm for use with Nd:YAG lasers.
Please contact us if your application requires a Laser Output Coupler with a custom design wavelength, size, or reflectivity.
