一直以來,對(duì)于乙炔鎖頻激光系統(tǒng)的科學(xué)研究,要求1542nm種子激光器具有窄線寬、無跳模、高可靠特性。例如在頻率梳、光譜學(xué)、計(jì)量學(xué)或激光冷卻及俘獲的科研領(lǐng)域,長久的穩(wěn)定性和精確的波長控制對(duì)于鎖定和穩(wěn)定波長至關(guān)重要。

基于KOHERAS BASIK X15的高穩(wěn)定和窄線寬激光器系統(tǒng)

基于乙炔鎖頻激光技術(shù),可以獲得更高的波長穩(wěn)定性系統(tǒng), 對(duì)此,NKT Photonics針對(duì)1542nm激光器優(yōu)化產(chǎn)品性能,目前Koheras BASIK X15已經(jīng)逐步成為基于乙炔鎖頻系統(tǒng)中種子激光器的選擇。更為重要的是,Koheras BASIK X15模塊是目前商用級(jí)別中線寬最窄且無跳模的激光器,洛倫茲線寬<100Hz。

基于乙炔吸收的穩(wěn)頻激光器系統(tǒng)結(jié)構(gòu)如上圖所示,其中種子激光是NKT Photonics的Koheras BASIK X15,波長為1542nm。

相位噪聲指標(biāo)規(guī)格如下:

Koheras BASIK X15既可以用于石油鉆井平臺(tái),因?yàn)槠渚哂懈叩目煽啃?,也可以用于科研?shí)驗(yàn)平臺(tái),因其具有良好的規(guī)格指標(biāo)。

Koheras光纖激光器結(jié)構(gòu)緊湊,在惡劣環(huán)境中可以正常運(yùn)行的壽命超過10年,且故障率低于1%,因其優(yōu)異的光學(xué)和結(jié)構(gòu)設(shè)計(jì),使得Koheras激光器免校準(zhǔn)和免維護(hù),使用起來更加便捷且可靠。

NKT Photonics工業(yè)級(jí)OEM激光器結(jié)構(gòu)設(shè)計(jì)可靠、抗環(huán)境影響能力強(qiáng),無論室外和室內(nèi)的工作環(huán)境,都可以保證性能指標(biāo),其已經(jīng)為眾多先進(jìn)的實(shí)驗(yàn)室提供了激光器,例如丹麥國家計(jì)量研究所和尼爾斯玻爾研究所的光學(xué)和光子學(xué)實(shí)驗(yàn)室等。

NKT Photonics已經(jīng)銷售了超過15000臺(tái)Koheras激光器,該激光器可以用于石油鉆井平臺(tái)勘探、潛艇勘察、風(fēng)力渦輪機(jī)檢測(cè),甚至在太空探索中也有應(yīng)用。NKT對(duì)于窄線寬激光器的研究已經(jīng)超過20年,并且NKT在窄線寬激光領(lǐng)域會(huì)持續(xù)前進(jìn),相信不久的將來,它將出現(xiàn)在您的實(shí)驗(yàn)室中。
