ALPHALAS宽带激光晶体波长调谐装置

借助 ALPHALAS 出品的波长调谐器件，可对 Ti:Sapphire、Yb:YAG、Yb:KGW 等各类宽带激光晶体，以及染料激光器、光学参量发生器实现发射波长的高效调谐。相关器件包含反射式与透射式衍射光栅、腔内标准具、色散棱镜及利奥滤光片。

布儒斯特角取向双折射片凭借极低损耗与宽调谐区间，调谐效果尤为出色。该产品常备现货，标准厚度覆盖 1 mm 至 10 mm，同时可按需定制规格。配套双折射基材选用晶体石英(适用光谱区间 200 … 2600 nm)与 MgF₂，其中 MgF₂可适配 150 nm～6500 nm 超宽光谱波段。针对波长最长至 19 µm 的远红外激光器，ALPHALAS 可供应特种红外双折射利奥滤光片。

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.
