Although a high-power diode laser operates at a relatively modest brilliance, optimized micro-optics make it well-suited for the rapid and precise cut
A high power laser diode test system is disclosed which includes a housing body defining at least one device test module compartment therein, a power supply, the system controller, and thermal control system positioned within the device test module compartment, a device test module having at least...
By observing a few simple rules that govern diode lasers’ properties, driving them loses much of its mystery. Below its threshold current, a diode laser emits LED light with spontaneous emission only. At the threshold current and above, it begins to generate laser light, and the optical outpu...
while modern laser techniques can resolve optical wavelengths separated by less than 10−10nanometre. The frequency with which the electromagnetic wave oscillates is also used to characterize the radiation. The product of the frequency (ν) and the wavelength (λ) is equal to the speed of light...
To mitigate these trade-offs, we enhanced a confocal laser scanning microscope with an asynchronous read-out single-photon avalanche diode array detector. This detector provides an image of the particle’s emission, precisely reflecting its position within the excitation volume. This localization is ...

In order to test the laser in a spectroscopic applica- tion, we recorded the saturation spectra of the rubidium D2 line (Fig. 6). The intensities of pump and probe beam were 5 mW and 150 µW respectively, the beam diameters were approx...
Featuring a compact footprint and convenient aiming beam, the SF2500/10 fiber-coupled laser system from Dilas has an output power of 2.5kW at 980 nm.
Improvements to the electronics and better temperature & laser power control will improve sensitivity to this level, however, we caution that reducing the signal noise floor on its own may not be sufficient because the device may suffer from saturation effects at small concentrations in a similar ...
