QPC laser

AMS Technologies has introduced Quintessence Photonics' (QPC) new laser designed to deliver high power in a single mode beam for seeding fiber and solid state lasers and for use in direct applications.

The seed laser can produce single-frequency beams of up to 1.5W CW at 1,064nm and up to 1W CW at 1,550nm, about 10 times the power output from existing diode-based seed lasers.

The seed laser is based on QPC's BrightLase singlemode laser technology which recently demonstrated industry-leading single-frequency powers exceeding 3W at conversion efficiencies greater than 50 percent.

The QPC design exploits a two-part chip that combines a low power section and an amplifying section. It employs a semiconductor chip mounted onto a heat sink with hard solder and optional single-mode fiber coupling is also available. As a result the design is much more compact than other high power seed lasers.

Substantially higher peak powers can be achieved under pulsed excitation conditions. The design simplifies laser systems for growth markets such as industrial, defence and communication systems.
