Testing and characterizing the light-generating devices at the very heart of photonics technology An important aspect of the development and manufacture of laser diodes is the so-called laser diode characterization, or laser IV curve. By applying increasing current to the laser diode so it that emi...

Techniques for characterizing the spatial and spectral properties of single TE mode laser diode beams are described. The spatial properties include beam size and shape, waist size and location, M 2 factor, far field divergence, and astigmatism. The spectral parameters include the wavelength and ...
Laser diode-fiber alignment and relative intensity noise (RIN) characterization are two crucial steps to the manufacturing of fiber pigtailed laser diode modules. Integrating both steps into a single automatic process can increase yield, improve the throughput and reduce manufacturing cost. This work pr...
Pulse detonation engine characterization and control using tunable diode-laser sensors 来自 掌桥科研 喜欢 0 阅读量: 36 作者:DW Mattison,CM Brophy,ST Sanders,L Ma,KM Hinckley,JB Jeffries,RK Hanson 摘要: One of the phenomena limiting the performance of pulse detonation engines (PDEs) is detonation...
Directed Energy offers a variety of laser diode drivers. DEI has laser diode driver instruments, standard modules and OEM modules for an array of applications.
However, accessing dynamic properties at small scales has remained a challenge owing to low-throughput and destructive characterization8,16,17 or lack of existing testing protocols. Here we demonstrate a high-throughput, non-contact framework that uses MHz-wave-propagation signatures within a ...
As a tool for the in situ characterization of meat quality, a hand-held Raman sensor head using an excitation wavelength of 671 nm was developed. A microsy... H Schmidt,K Sowoidnich,Kronfeldt, Heinz-Detlef - 《Applied Spectroscopy》 被引量: 63发表: 2010年 Applications of non-destructive...
The hardware is configured around two semiconductor diode lasers having output wavelengths of 1064nm and PIC microcontroller based embedded system to drive these lasers. The laser seeker head was extensively tested using this advanced test system. The test results are presented in the paper. 展开 ...
