Our square silver-coated mirrors are available in 1/2", 1", and 2" sizes and have the highest reflectance of all metal-coated mirrors for the visible wavelength range. Silver is an ideal choice for high reflectance from 450 nm to 20 µm. In order to protect the mirrors from oxidation, they have an overcoat of SiO2. Though the overcoat helps to protect silver from tarnishing, high humidity environments should be avoided.

Our protected aluminum, silver, and gold coatings exhibit exceptional broadband reflectance and are practical for many applications that are insensitive to the wavefront of a beam. Other typical uses for these mirrors include single-use applications where the experiment itself damages the mirror. A variety of diameters and square sizes are offered, including an 8" x 8" protected aluminum version. Please see the Specs tab for more details on these mirrors.

Our round protected aluminum mirrors are available in Ø1/2", Ø1", and Ø2" sizes, and exhibit average reflectance in excess of 90% in the 450 nm to 2 µm range and 95% in the 2 µm to 20 µm range. A protective SiO2 overcoat is layered over bare aluminum, creating an oxidation-resistant surface which has a smaller chance of tarnishing than protected silver in a high humidity environment. The mirror surface can be cleaned using a wipe or swab soaked in methanol. For more on cleaning optics, see our optics handling and cleaning tutorial.

Frequency multiplying is a technique used to produce a wavelength that is one half (or one third or one quarter) of the fundamental wavelength of a laser. Using this technique the 1.06µm Nd:YAG beam can be produced 'frequency doubled' at 0.53µm, or with a wavelength of 0.266µm if 'frequency quadrupled', for example. The potential benefits of this are that the shorter wavelength will often be absorbed better by the material being processed and can also be focussed to a smaller spot size, thereby increasing available power density. These 'frequency multiplied' advantages however come at a cost of quite significantly lower average power output than at the fundamental frequency of the laser concerned, due to the inefficiency of the process. Commercial frequency doubling relies on non-linear crystals. As a laser beam passes through the crystal, non-linear interactions between the beam and the material (e.g. lithium borate with Nd:YAG), generate electromagnetic waves at twice the laser frequency. Generation of third and fourth harmonics using non-linear crystals is usually a multistep process. Generating a second harmonic, then mixing it with the fundamental wavelength in another non-linear crystal, so the frequencies combine, produces the third harmonic. To produce the fourth harmonic, the output of a second harmonic generator is passed through a second frequency doubler. Clearly generation of frequency tripled and quadrupled laser light is highly inefficient.
