借助 ALPHALAS 出品的波長(zhǎng)調(diào)諧器件，可對(duì) Ti:Sapphire、Yb:YAG、Yb:KGW 等各類寬帶激光晶體，以及染料激光器、光學(xué)參量發(fā)生器實(shí)現(xiàn)發(fā)射波長(zhǎng)的高效調(diào)諧。相關(guān)器件包含反射式與透射式衍射光柵、腔內(nèi)標(biāo)準(zhǔn)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(diào)諧區(qū)間，調(diào)諧效果尤為出色。該產(chǎn)品常備現(xiàn)貨，標(biāo)準(zhǔn)厚度覆蓋 1 mm 至 10 mm，同時(shí)可按需定制規(guī)格。配套雙折射基材選用晶體石英(適用光譜區(qū)間 200 … 2600 nm)與 MgF?，其中 MgF?可適配 150 nm～6500 nm 超寬光譜波段。針對(duì)波長(zhǎng)最長(zhǎng)至 19 µm 的遠(yuǎn)紅外激光器，ALPHALAS 可供應(yīng)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.
