HHL Package

The HHL(High Heat Load) package is one of the largest industry standard package available. The HHL package is common for applications with a large heat load (2W and higher optical power). High-power CW lasers in HHL packages are common in medical applications, welding and marking equipment, and pumping sources for solid state lasers.

It's a hermetically sealed package for fiber-coupled high power laser module, thick pins can take heavy electrical current and the package can solder a window on the lid as requested.
