借助 ALPHALAS 出品的波長調諧器件，可對 Ti:Sapphire、Yb:YAG、Yb:KGW 等各類寬帶激光晶體，以及染料激光器、光學參量發生器實現發射波長的高效調諧。相關器件包含反射式與透射式衍射光柵、腔內標準具、色散棱鏡及利奧濾光片。

布儒斯特角取向雙折射片憑借極低損耗與寬調諧區間，調諧效果尤為出色。該產品常備現貨，標準厚度覆蓋 1 mm 至 10 mm，同時可按需定制規格。配套雙折射基材選用晶體石英(適用光譜區間 200 … 2600 nm)與 MgF?，其中 MgF?可適配 150 nm～6500 nm 超寬光譜波段。針對波長最長至 19 µm 的遠紅外激光器，ALPHALAS 可供應特種紅外雙折射利奧濾光片。

Efficient tuning of the emission wavelength of various wideband laser crystals like Ti:Sapphire, Yb:YAG, Yb:KGW as well as dye lasers and optical parametric generators is achieved by means of wavelength tuning devices offered by ALPHALAS . These include reflection and transmission diffraction gratings, intracavity etalons, dispersive prisms and Lyot filters.

Especially efficient are Brewster-oriented birefringent plates due to the very low losses and wide tuning ranges. These are available from stock with standard thicknesses from 1 mm to 10 mm, but also as customer-specific designs. The offered birefringent materials are crystal quartz for the spectral range 200 … 2600 nm and MgF2. The latter can be used in the extremely wide spectral range from 150 nm to 6500 nm. For far infrared wavelengths and lasers, up to 19 µm, ALPHALAS offers unique IR birefringent Lyot filters.
