AMS Technologies introduces QPC's (Quintessence Photonics) latest laser designed to deliver high power in a single-mode beam for seeding fibre and solid-state lasers and for use in direct applications. The seed laser can produce single-frequency beams of up to 1.5W CW (continuous wave) at 1064nm and up to 1W CW at 1550nm, about 10 times the power output of existing diode-based seed lasers. The seed laser is based on QPC's BrightLase single-mode laser technology, which demonstrates industry-leading single-frequency powers exceeding 3W at conversion efficiencies greater than 50%. The design exploits a two-part chip that combines a low-power and an amplifying section.
