Wasatch PhotonicsVPH激光脈沖壓縮光柵?
產(chǎn)品描述：
Wasatch Photonics enhanced volume phase holographic (VPH) gratings 對(duì)于高功率超快激光的脈沖壓縮以及伸展是非常好的一種選擇。這是光柵是目前市場上高衍射效率的光柵。獲得更多的光子是我們所做的好的，不像表面浮刻光柵，我們的光柵可以更便于操作和容易清洗。有部分光柵我們備有庫存在香港，可以隨時(shí)發(fā)貨與此同時(shí)我們也可以接受客戶的定制服務(wù)滿足客戶個(gè)性化的定制需求。
產(chǎn)品特點(diǎn)：
全波段高傳輸
- 低波前畸變，小散射
- 全衍射均勻衍射效率
- 小光束畸變孔徑
- 高脈沖能量應(yīng)用的理想選擇
- 堅(jiān)固的設(shè)計(jì)，便于清洗
- 大光學(xué)設(shè)計(jì)靈活性
效率高，均勻性強(qiáng)，波前畸變小
我們的體相全息光柵在性能上是優(yōu)異的，并且比傳統(tǒng)的表面浮雕光柵具有更大的耐用性。我們專有的工藝將光柵結(jié)構(gòu)封裝在一個(gè)堅(jiān)固的封裝中，便于操作和清潔。許多設(shè)計(jì)師使用傳輸脈沖壓縮腔設(shè)計(jì)，靈活，緊湊，往往折疊布局。我們均勻的效率、小的散射和低的波前畸變確保了它們得到短、干凈的脈沖。

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
