PD-LD激光二極管，VBG光柵技術產品

PD-LD是一家光電子公司，總部在美國新澤西州彭寧頓，主要生產并裝配帶尾纖或者帶光纖插口的二極管激光器、LED、探測器、高功率的脈沖激光以及光纖通信中的雙向裝置。是新澤西州發(fā)展快的技術性公司，PD-LD公司同時也生產客戶定制的VBG零件，以及在拉曼光譜，高功率激光，顯示器等方面需要使用的內置VBG的激光。

PD-LD’s的有源器件和無源器件，無論標準的或定制的，總有器件能滿足客戶的產品要求，客戶遍布光通訊，傳感，自動化，航空，光譜學，醫(yī)學工業(yè)等各個領域，且都為上述領域的領導者。PD-LD不僅僅只限于為芯片提供封裝，而且擁有一些世界級的光學專家，他們擁有高深的專業(yè)知識，能滿足客戶提出的苛刻的定制要求。

PD-LD公司是VBG光柵技術的全球先驅，近剛剛獲得一項新，可以使激光二極管結構更加簡單，效率更加穩(wěn)定。這項發(fā)明使用的VBG技術可以改善多種發(fā)光裝置的輸出特性，如激光器，激光二極管，發(fā)光二極管等。這項用來改進技術，并且已經廣泛使用在拉曼光譜，激光泵浦以及光纖通信中。其中提供了一個修改或者改進激光輸出光譜的方法。使用了一個特殊的光學元件提高激光的穩(wěn)定性。

“這項新的發(fā)明使得PD-LD公司的數達到了14個，這也證明了我們在VBG領域的領導地位，立足在我們已有的基礎上，在工業(yè)化以及應用方面，我們的數將不斷增長�！盤D-LD公司的總裁兼CEO弗拉基米爾博士如此說到。

PD-LD公司的輸出波長為523nm或者785nm的新型拉曼激光光源，采用光纖耦合輸出，通過使用PD-LD公司專有的VBG-stabilized的808nm激光器，泵浦倍頻到532nm的YAG晶體，實現了50mW的輸出功率。 該光源具有窄線寬、高功率、緊湊及牢固的設計，使其特別適用于便攜儀器應用。其小巧的外形和簡單的接口使其成為工業(yè)、軍事和應用的理想選擇。還推出了TO封裝光源，激光芯片被密封在TO-9或者TO-56中，整個TO結構整合在一個銅質的散熱器中，以達到光學特性。出光口安裝了非球面棱鏡以及PD-LD公司的VBG，對光路進行壓縮，并且得到窄帶激光，是拉曼光譜的理想光源。在原先LML-785.0RB-XX的基礎上，通過改變制冷方式，使得光源盒可以在-15攝氏度至50攝氏度的環(huán)境中工作，由此衍生出新的型號LML-785.0CB-XX。新款的產品同樣繼承了上代產品的緊湊型外觀，只有76*64*17mm的大小，在這么大的體積上整合了5V的電壓輸入，可編程的USB等接口，光輸出通過一個FC/APC接口耦合到光纖中，使用十分便捷。

VBG wavelength stabilization of high power laser diodes and laser diode arrays

Another major application of VBG technology is the wavelength stabilization of high power laser diodes and laser diode arrays, e.g., for more efficient pumping of solid state lasers and fiber lasers. Some dramatic improvements have been achieved:

Narrow line width, < 0.5 nm
Precise center wavelength control, +/- 0.5 nm
Reduced thermal drift, ~0.01 nm/C

VBG Wavelength Stabilized High Power Laser Diodes – Single Emitters

VBG wavelength stabilization can be applied to laser diodes of any power or wavelength. Our standard products in the single emitter line are 1, 2 and 3 Watt diodes in C-mount, TO 3 and 9 mm can packages. Standard wavelengths are 785 nm, 808 nm, 938nm and 976 nm. Please inquire about the availability of other wavelengths.

The geometry and dimensions of VBG stabilized diodes are comparable to standard high power laser diodes. VBG stabilized diodes have many important applications, e.g., in diode pumping of solid state lasers, in spectroscopy and sensing, and in medical and military areas.
