皮秒半導體激光器

 

advanced Laser Diode Systems A.L.S.公司的PiLas半導體激光器可以提供皮秒量級的脈沖輸出,脈寬可小到18ps。此類皮秒半導體激光器的波長範圍廣,可覆蓋375nm1550nm這一範圍。其峰值功率從20mW1000mW不等。其抖動很小,僅為3ps4ps

一套标準系統包括驅動器、激光頭和光學附件部分。

根據重複頻率不同可劃分兩類:01MHz重複頻率可調和100MHz固定重複頻率。

PiLas

The Picosecond Laser Diode Systems

The PiLas Systems are diode lasers emitting very short optical pulses with pulse widths down to 18 ps (FWHM), depending on the laser diode used. The standard system consists of a digital electrical pulse generator EIG, an optical head with a laser diode and a collimating optics (paralleling optics, single mode fiber output or multimode fiber output versions are also available). The laser diodes of the various models are pre-configured to emit on a fixed wavelength within a spectral range between 375 nm and 1550 nm, i.e. from ultraviolet to infrared, based on all commercial available diode wavelengths. Typical peak powers are in the range of 20 mW to more than 1000 mW, depending on the laser diode used. The jitter between electrical trigger and optical pulse is about 3 ps - 4 ps. Special wavelengths or specifications are – if technically possible – available on request.

Different optical arrangements are possible
A graphical review of the different optical versions is given in the following link: PiLas optical setup
Two Versions of PiLas-Systems are available:
1 MHz PiLas
(repetition rate from single shot to 1 MHz)
Fast PiLas
(100 MHz fixed, other frequencies on request)
