Diode pumped passively Q-switched micro laser AltLAS
Description
Yb:YAG micro laser produces high energy pulses at high repetition rates with medium peak power.
There are two operation modes (AltLAS-C): internal trigger with several fixed pulse repetition rates and external trigger mode where laser can generate single pulse as well as any periodic or non periodic pulse train*.
*minimal duration between adjacent pulses at least 100 microseconds in AltLAS - C - 10kHz model
Yb:YAG micro laser is the latest development of Fibercryst R&D department. This device combines high repetition rate and powerful pulses with excellent beam quality and very high output power. Due to unique characteristics of Yb:YAG laser crystal we can propose very wide range of different parameters on request.
