Picosecond Diode Lasers, Pico-LDs, are designed and manufactured by CrystaLaser. The lasers produce <80 ps short laser pulses with peak powers as high as 3 W. The Pico-LDs are cover the wavelength ranging from 375 nm to 1650 nm. Our picosecond diode laser system includes picosecond diode la...
Laser system B based on device B is tunable from 666 to 685nm. As high as 1.05W output power is obtained around 675.67 nm. The emission spectral bandwidth is less than 0.07nm throughout the tuning range, and the beam quality factor M(2) is 1.13 at an output power of 0.93W. Laser ...
the latter being the more popular. In fact, very few dispersion instruments are sold today but many are still used in the field and so their characteristics will be discussed. All multichannel detectors require a broad emission light source such as deuterium or the xenon lamp, the deuterium lam...
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 ...
A dual-wavelength diode laser with sub-MHz narrowband emission at 785 nm is presented. The device is investigated for both emission lines up to an optical power of 150 mW. A stable spectral distance between the two laser wavelengths of 0.6 nm (10 cm-1) over the whole power range is ...
Abstract By alloying GaN with AlN the emission of AlGaN light-emitting diodes can be tuned to cover almost the entire ultraviolet spectral range (210–400 nm), making ultraviolet light-emitting diodes perfectly suited to applications across a wide number of fields, whether biological, environmental,...
The stimulated emissions from semipolar InGaN laser diode (LD) structures grown on ( 11 2 2 ) GaN substrates are observed at room temperature under photopumped conditions. The measured emission peaks are in the photon energy range from 2.62 eV (474 nm ) to 3.05 eV (405 nm ) , and the...
Within the scope of this ex vivo study, the cut efficiency was investigated with eight diode laser wavelengths in the range from 400 to 1500 nm. Incisions on porcine gingiva samples were generated in CW-mode at a power range of 0.5–4 W using a bare fiber (∅= 320 μm) in contac...
1. A function-generator triggers a 798 nm laser with a repetition rate of 0.25 to 1 MHz. The emitted light pulse of ≈1 ns length gets attenuated in a neutral attenuator to <0.1 photons per pulse on average and arrives at the active area of the respective detector in use. The...
In order to realize the GaAs laser diode wavelength of 940nm, since its transition energy is about 1.319eV, which is much smaller than the band gap of GaAs, the usual matching GaAs/AlGaAs (λ=0.7-0.9um) and InGaAsP/InP (λ=1.1-1.65um) is difficult to achieve. The emission wavelength ...
