Semiconductor Lasers & Transmitters

Select the source for receiver wavelength and optical interface; review optical output, control, coupling and cooling separately.

Semiconductor lasers & transmitters

Match receiver wavelength, optical interface and optical power.

Liquid-cooled configurations; wavelength and 1–4 channels depend on version. Confirm power allocation, optical interfaces and safety interlocks.

808 nm / 20 W laser: specifications and documentation

20 W is the typical laser optical output, not the electrical output of an LPC receiver. System selection must account for fiber and connector compatibility, transmission losses, cooling and receiver operating conditions.

Optical and electrical parameters

Datasheet test condition: water temperature 25°C. A dash indicates a value not specified in the source specification.
