STANDA-Q1SH671-Active Q-switched Laser

Wavelength of 671nm; single pulse energies up to 20uJ are available in less than 200ps

Standa-Q1SH671 is a very compact actively q-switched diode pumped and frequency doubled Nd:YVO4 laser, utilizing novel resonator architecture to generate picosecond laser pulses at a wavelength of 671nm with excellent beam quality. Single pulse energies up to 20uJ are available in 150-250ps laser pulses delivered at repetition rate of up to 100Hz.


Standa-Q1SH671 enables such applications as Disease Diagnostics, Biomedical Imaging, and Raman Spectroscopy.


Laser head of Standa-Q1SH671 fits into the same package as STANDA-Q1 laser head does, and utilizes the same STA-01 laser controller.
The main laser parameters can be modified to better fit the customer’s application. OEM version of STANDA-Q1SH671 laser system is also available. OEM controller needs 7.5 V DC power supply and has USB or RS-232 interface to communicate with a PC. The OEM controller appearance will be similar to our STA-01-OEM control unit.
