Construction and characterization of a simple but flexible, low cost diode laser system for atomic spectrometry is reported. Detailed electronic circuit layouts of the diode laser current controller, supplying maximum 1300 mA current with 1 mA resolution, and functional description of all other ...
A DFB laser is alaser diode or optical fiber laserwith a low linewidth grating that extends throughout the cavity rather than simply at the opposite edges. Because they are single-frequency laser diodes, distributed feedback lasers have short linewidth and effective side modes. Distributed Feedback...

This paper reports the implementation of two critical technologies used in light detection and ranging for space applications: (1) a microchip Q-switched laser breadboard; (2) a breadboard of an indium gallium arsenide avalanche photodiode working at 292 K with high reverse polarization voltages. ...
In this pump laser, the output beam from a continuous wave (CW), single-longitudinal-mode laser diode (LD)-pumped, Yb-doped fiber laser is arbitrarily shaped with the programmable optical pulse shaper and amplified in a rod pre-amplifier, a regenerative amplifier, and two rod main amplifiers...
which is inserted in the pump beam path before the quartz plate (Fig. 1.39(a)). On the other hand, the probe pulse goes into another λ/2 plate after passing through the quartz plate and then into a polarized beam splitter (PBS) placed at the front of a photodiode-detector (PD equip...
