The Wyvern™ 1000  Series amplifier by KMLabs is the only variable repetition rate amplifier in today’s high energy kHz class market. Offering industry leading “hands-off” computer-controlled tuning of repetition rates and the highest scalable pulse energies available in the market. Make sure you answer these questions before buying any ultrafast amplifier, and future-proof your system!

Utilizing a simple Single-Stage design the Wyvern 1000 is a cut above its closest competitors that  require more complex two-stage or dual-head architectures in order to reach similar power levels.  Our patented Cryogenic technology eliminates thermal lensing and heat management issues that limit the competition.
