Q-Pico - Series

Q-Pico Series, Q-switched Nd:YAG laser, diode pumped

Q Pico

The Q-PICO diode pumped laser system is a perfect choice for OEMs and system integrators who produce picosecond based systems for medical and aesthetic use. Optical components of robust master oscillator are sealed from environment in order to avoid contamination and ensure long-term reliable operation. Oscillator and compressor are mounted on temperature controlled plate using TEC coolers for excellent temperature stability.

The newly developed Quantas Picosecond laser system is a perfect choice for OEMs and system integrators who produce picosecond laser systems for medical and aesthetic use. It combines innovative pulse compression technique with robust master oscillator. System consist of diode pumped actively Q-switched short pulse nano‑second laser and non-linear solid state compressor. Master oscillator is designed to produce short pulses with high output energy. Optical components of master oscillator are sealed from environment in order to avoid contamination and ensure long-term reliable operation of the laser. Master oscillator and pulse compressor are mounted on common plate that is temperature controlled using TEC coolers with good temperature stability. Laser controller has Ethernet interface for convenient monitoring and control from personal computer. The compact design is easy to integrate into amplifier system. Sub‑nanosecond pulse duration, high pulse energy, stable long term output specs, makes Quantas PICO lasers ideal source for system integrators.
