Current Pulsers and Laser Diode Drivers (Pulsed Current)
-
These instruments generate current pulses whose amplitude is largely independent of the load voltage. This makes them ideal for pulsing device whose voltage may vary with time (for instance, the voltage drop of laser diodes may vary with temperature, or explosive squibs which change impedance during ignition). This voltage independence is a trade-off with speed. If faster rise times are required, consider using pulsed voltage instruments instead.

It is leaded to get rid of the inefficiency of expense, at which various types of expensive united source module needed are purchased. By operating monitoring PD and high-performance processor that are installed inside the module, the output power and temperature of LD can be driven accurately and stably. The laser diodes can be modulated internally in square, sinusoidal, and triangular waves and its output power and temperature can also be maintained the level set by the user. In order to realize the various functions, the efficient and multi-functioned control programs with high speed processor, LCD monitor or GUI for remote control are available.

LIV – High-power Laser Diode Testing
-
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 emits light, the optical output is measured together with the voltage drop across the diode element. The resulting LIV curve reveals important clues about the quality of manufacture and the performance of the laser diode, enabling a pass/fail decision to be met.

In-Situ Cross- Stack Laser Analyzer
-
LS25 is an in-situ analyzer for non-contact measurement of the concentration of gases. The measuring principle of the LS25 is based on the principle of single line spectroscopy (Tunable diode laser absorption spectroscopy, TDLAS). A single cross-sensitivity-free absorption line of the gas to be measured is selected in the near infrared range. A single-mode diode laser operating at room temperature scans the respective absorption line. By using an opposite receiver, the absorption caused by the sample gas is measured and from this the concentration is calculated. An automatic correction for pressure and temperature changes is possible. In addition, the transmission is displayed respectively output as a signal for preventive maintenance.
