Wasatch PhotonicsVPH激光脉冲压缩光栅?
产品描述：
Wasatch Photonics enhanced volume phase holographic (VPH) gratings 对于高功率超快激光的脉冲压缩以及伸展是非常好的一种选择。这是光栅是目前市场上高衍射效率的光栅。获得更多的光子是我们所做的好的，不像表面浮刻光栅，我们的光栅可以更便于操作和容易清洗。有部分光栅我们备有库存在香港，可以随时发货与此同时我们也可以接受客户的定制服务满足客户个性化的定制需求。
产品特点：
全波段高传输
效率高，均匀性强，波前畸变小
我们的体相全息光栅在性能上是优异的，并且比传统的表面浮雕光栅具有更大的耐用性。我们专有的工艺将光栅结构封装在一个坚固的封装中，便于操作和清洁。许多设计师使用传输脉冲压缩腔设计，灵活，紧凑，往往折叠布局。我们均匀的效率、小的散射和低的波前畸变确保了它们得到短、干净的脉冲。

衍射效率：
We measure every transmissive VPH grating to ensure
exceptional 1st order diffraction efficiency. Many other
vendors report only theoretical graphs of total diffraction
efficiency. This includes diffraction into other orders, and
is not truly representative of actual performance.
OEM SOLUTIONS
At Wasatch Photonics, we understand the processes & metrology needed to manufacture high quality pulse compression gratings in volume, at wavelengths up to 2500 nm. We work collaboratively with our OEM partners on each design and test procedure, establishing customer-specific test fixtures at our site to reduce the burden of inbound testing at your site for guaranteed system-ready performance.Take the Wasatch VPH challenge and reduce your pulse length by up to 15%!
