調(diào)制器和固定移頻器
調(diào)制器:
聲光調(diào)制器用于改變?nèi)肷浼す馐膹姸龋ㄕ{(diào)幅,AM)。調(diào)制可以是數(shù)字的(開/關(guān))或模擬的(正弦波、方波、線性、隨機……)。
調(diào)制器的關(guān)鍵參數(shù)是其上升/下降時間,它定義了可實現(xiàn)的調(diào)制“速度”或幅度調(diào)制帶寬。上升/下降時間與調(diào)制器內(nèi)的光束直徑成正比。因此,激光束必須聚焦在調(diào)制器內(nèi)部以達(dá)到快速上升時間。
固定移頻器:
聲光移頻器利用聲光相互作用實現(xiàn)激光頻移。激光波長的頻移量為載波 RF 頻率。頻移可以是正值或負(fù)值,具體取決于角度配置設(shè)計。調(diào)制器用作固定移頻器。

脈沖選擇器
脈沖選擇器是一種電控光學(xué)開關(guān),用于從快速脈沖序列中提取單個脈沖。在大多數(shù)情況下,短脈沖和超短脈沖是由鎖模激光器以脈沖序列的形式產(chǎn)生的,脈沖重復(fù)率約為 10 MHz – 幾 GHz。由于各種原因,經(jīng)常需要從這樣的脈沖串中挑選特定的脈沖,即只傳輸特定的脈沖并阻止所有其他脈沖。這可以通過脈沖選擇器來完成,脈沖選擇器本質(zhì)上是一個電控光門。

偏轉(zhuǎn)器和可變移頻器
布拉格配置提供單個一階輸出光束,其強度直接與 RF 控制信號的功率相關(guān),而其角度與 RF 頻率直接相關(guān)。
通過改變頻率,可以修改輸出激光束角度。偏轉(zhuǎn)器用于在一定角度范圍內(nèi)掃描激光束,或精確控制激光束的輸出角度。通過改變頻率,一階光束也被移頻了 RF 載波頻率的量:它就像一個可變移頻器。
偏轉(zhuǎn)器的主要參數(shù)是1. 偏轉(zhuǎn)角范圍和 2. 分辨率。
偏轉(zhuǎn)角范圍是激光束的角度變化:它與設(shè)備的頻率范圍有關(guān)。偏轉(zhuǎn)器的分辨率是偏轉(zhuǎn)器可以處理的不同方向的數(shù)量:它與偏轉(zhuǎn)角范圍和激光發(fā)散角有關(guān)。
兩個偏轉(zhuǎn)器可以串聯(lián)和成直角使用,以提供完整的二維掃描。

AO可調(diào)濾波器 AOTF
AOTF 是一種固態(tài)電子可調(diào)諧帶通濾波器,它利用各向異性介質(zhì)內(nèi)部的聲光相互作用。這些濾光片可與多線光源(混合氣體激光器、激光二極管……)或?qū)拵Ч庠矗瘹鉄簟Ⅺu素?zé)?hellip;…)一起使用。它們允許從入射光中選擇并傳輸單個或多個波長。
AA 提出了一系列基于 TeO2的 AOTF。濾光片的設(shè)計旨在在每個波長范圍內(nèi)獲得性能并滿足大多數(shù)應(yīng)用:分辨率低至 1 nm,視場高達(dá) 20 度,孔徑高達(dá) 10 mm……
在大多數(shù)情況下,可調(diào)諧濾波器的濾波輸出是共線的,以便于使用這些設(shè)備,并滿足光纖尾纖輸出。隨機輸入偏振將被分成兩個正交偏振(階數(shù) -1 和 +1)。

多通道可調(diào)濾波器AOTFnC
AOTFnC 是一種特殊的聲光可調(diào)濾波器,它利用二氧化碲晶體 (TeO2) 內(nèi)部的各向異性相互作用來獨立或同時控制入射 UV 光或可見激光(白色激光、Ar+、Kr+、HeNe、DPSS、染料…)。
最多可以混合和單獨調(diào)制 8 條不同的線,以生成不同的色度圖案。AOTFnC 的特定晶體切割產(chǎn)生良好的衍射效率 (> 90%)、窄分辨率 (1-2 nm)、低線間串?dāng)_和高消光比。
0 階和 1 階之間的大分離角以及出色的輸出色度共線性(<0.2 至 <0.3 mrd)使該 AOTF 成為自由空間或光纖尾纖應(yīng)用的強大工具。其相關(guān)的熱穩(wěn)定性保持穩(wěn)定的衍射效率,并通過單模光纖尾纖顯著減少光束漂移。這是高靈敏度應(yīng)用的主要優(yōu)勢。

光纖激光器
光纖激光器或光纖激光器是一種激光器,其中有源增益介質(zhì)是摻有鉺、鐿、釹、鏑、鐠和銩等稀土元素的光纖。光纖非線性,例如受激拉曼散射或四波混頻也可以提供增益,因此實際上用作增益介質(zhì)。與大多數(shù)其他類型的激光器不同,光纖激光器中的激光腔是通過熔接不同類型的光纖而整體構(gòu)建的;注意的是光纖布拉格光柵在這里取代了傳統(tǒng)的介質(zhì)鏡以提供光學(xué)反饋。
為了泵浦光纖激光器,幾乎只使用半導(dǎo)體激光二極管或其他光纖激光器。光纖激光器可以有幾公里長的有源區(qū)并提供非常高的光學(xué)增益。它們可以支持千瓦級的連續(xù)輸出功率,因為??纖維的高表面積與體積比可以實現(xiàn)高效冷卻。光纖波導(dǎo)特性減少或消除光路的熱畸變,從而產(chǎn)生通常衍射受限的高質(zhì)量光束。與同等功率的棒狀或氣體激光器相比,光纖激光器還具有緊湊的布局,因為光纖可以彎曲成小直徑并盤繞。其他優(yōu)勢包括高振動穩(wěn)定性、延長使用壽命和免維護交鑰匙操作。許多高功率光纖激光器都基于雙包層光纖。增益介質(zhì)構(gòu)成光纖的纖芯,纖芯被兩層包層包圍。激光模式在纖芯中傳播,而多模泵浦光束在內(nèi)包層中傳播。外包層限制了這種泵浦光。這種布置允許纖芯用比其他方式在其中傳播的功率光束高得多的能量泵浦,并允許將亮度相對較低的泵浦光轉(zhuǎn)換為亮度高得多的信號。因此,光纖激光器和放大器有時被稱為作為“亮度轉(zhuǎn)換器”。
應(yīng)用包括:材料加工、電信、光譜學(xué)和醫(yī)學(xué)。
