Efficient High Power Diode-Side-Pumped Intracavity-Doubled Continuous Wave Green Laser

The Narrow Pulse-Width Laser-Diode End-Pumped Nd:Yvo4/Lbo Green Laser

“…The end-pumping technique, which is a more effective way to match the size of pump beam and cavity mode, can improve the beam quality and increase the optical conversion efficiency. In 2004 Yaojianquan adopted LBO SHG crystal to generate green light with pulse width of 130ns,power of 104W [4].High-power green laser is not uncommon [5][6][7][8][9] ,but High-power, high-repetition-frequency narrow pulse End-pumped green lasers are few reported of.…”

Green-Beam Generation of 40 W by Use of an Intracavity Frequency-Doubled Diode Side-Pumped Nd:YAG Laser

“…In this Letter, stable and high-power green-beam generation is achieved based on our previous work [4,5] after further optimizing cavity parameters. The maximum output power of stable cw green is 40 W, corresponding to an optical-to-optical conversion efficiency of 9.7%.…”

基于电码型发生器的重复频率可调型超短光脉冲产生技术

“…In this letter, a novel method is proposed and demonstrated, which can be used to generate ultra-short optical pulse with tunable repetition rate (that is, tunable duty cycle). Therefore, this method is applicable to areas requiring ultra-short optical pulses with low repetition rate, such as OCDMA, multi-wavelength pulse generation [13] , photonic analog-to-digital conversion [14] , etc. In this method, a 10-Gb/s programmable electrical pattern generator (EPG) with a code length of 16 bits is applied on the in-cavity modulator of an actively mode-locked laser.…”
