摘要:
A ring-cavity synchronously-pumped optical parametric oscillator (OPO) is investigated based on periodically poled KTi:OPO4 (PPKTP).The wavelength of the signal wave covers from 1 000 to 1 500 nm,the output power is 32.3 mW,and idler wave spectrum range from 1 800 to 2 500 nm is detected.By inserting a BBO or BIBO crystal respectively,a stable and adjustable range from 450 to 650 nm light is obtained.Three to six wavelengths can be output simultaneously.
