Hybrid Laser Diodes for Pulsed Operations 905 nm Download Datasheet The LHCVN series incorporates a pulsed laser firing circuit into the same package as the laser diode. The hybridization of the driver permits much narrower pulse widths and faster rise times at lower voltage requirements than discrete laser drivers.
Pulsed LDD series. Pulsed laser diode drivers (LDDs) are designed to feed a semiconductor laser emitter with a desired pulsed current (QCW mode). The units are used in pulsed diode-pumped laser systems. All the units have high voltage and high power characteristics. There are many different options and configurations to choose from.
Continuous vs. pulsed operation Standard laser diodes are designed to emit CW radiation with power from a few milliwatts to a few watts. Heat removal and laser-threshold mini-mization are important considera-tions. As a result, these devices usu-ally are long enough to ensure ef-fective heat removal over their length and are often mounted on a ...

We demonstrated passively Q-switched operation of the Bessel-Gauss laser. To prevent excessive thermal load on the laser crystal, we used a quasi-CW pumping consisting of 1-ms pulses at a 200-Hz repetition rate. The pump power level was adjusted so that a single Q-switched pulse was obtained from a single pump pulse. By adding a Cr/sup 4+/:YAG crystal with an initial transmission of T/sub 0 ...
Pulsed laser. Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in continuous mode.

Pulsed-laser operation can be achieved by sending a CW laser output through an external modulator that acts as a switch allowing light to transmit for only short time periods (see Figure 1, left). This simple method has many disadvantages. Since most of the light is blocked by the modulator, the method is very inefficient.
This linear trend is apparent for continuous-wave (CW) operation diodes, as shown in Figure 2 for current 940 nm laser bars. The pulse length for pump diodes in pulsed lasers is close to the storage time of the gain media (Table 1). In this quasi-continuous wave (QCW) operation mode, the carrier and light distributions inside the semiconductor ...
Pulsed laser diodes are driven with high voltage, low duty cycle PWM pulses (usually ~1% duty cycle at hundreds of kHz) in order to reach 100 ns or faster pulse widths. Driving a pulsed laser diode with a smaller rise time provides higher resolution images and allows for a faster scanning rate. The short rise times required in driver ICs and in ...
A suitable kind of diode laser (typically an edge-emitting single-mode laser) can be mode-locked with active, passive or hybrid techniques. In any case, mode-locked operation means that a single ultrashort pulse (or in some cases a couple of equidistant pulses) circulates in the laser resonator.
The H Package long pulse laser diode array is designed specifically for direct diode applications (e.g. hair removal and plastic welding), and is offered in two dimensional configurations with long pulse operation from 0.5ms to 300ms at up to 150 Watts per bar operation.
