Efficient Second Harmonic Generation of a Diode - Laser - Pumped CW Nd : YAG Laser Using Monolithic MgO : L i m o 3 External Resonant Cavities
نویسنده
چکیده
We report 56% efficient external cavity resonant second harmonic generation of a diode-laser pumped, CW single-axial-mode Nd :YAG laser. A theory of external doubling with a resonant fundamental is presented and compared to experimental results for three monolithic cavities of nonlinear MgO : LiNb03. The best conversion efficiency was obtained with a 12.5 mm long monolithic ring cavity doubler, which produced 29.7 mW of CW, single axial mode 532 nm radiation from an input of 52.6 mW.

Second-harmonic generation of a continuous-wave diode-pumped Nd:YAG laser using an externally resonant cavity.
We report 13% second-harmonic conversion efficiency of a 15-mW, cw, diode-laser-pumped Nd:YAG oscillator. 2 mW of single-axial-mode 532-mm radiation was generated by externally resonant second-harmonic generation in a monolithic MgO:LiNbO(3) nonlinear crystal cavity. The measured finesse of 450 for the monolithic external cavity indicated that absorption and scatter losses in the doubler were l...

A monolithic doubly resonant optical parametric oscillator (OPO) fabricated from MgO:LiNbO(3) was pumped by a cw, frequency-doubled, diode-laser-pumped Nd:YAG laser. The threshold for cw operation was 12 mW, and pump depletions of up to 78% were observed two times above threshold. The total OPO output power was 8.15 mW, with a conversion efficiency for the incident pump of 34% and combined conv...
متن کاملPicosecond laser pulse generation in a monolithic self-Q-switched solid-state laser
We report the generation of laser pulses of 290-ps duration with 8-N pulse energy in single longitudinal mode and single transverse mode in a diode-end-pumped monolithic self-Q-switched Cr,Nd:YAG laser. The most commonly used method of generating picosecond laser pulses is the mode-locking technique. Mode-locking generally requires a light modulator such as an intracavity acousto-optical modula...
متن کاملEfficient GaAlAs diode-laser-pumped operation of Nd: YLF at 1.047 Mum with intracavity doubling to 523.6 nm.
The use of semiconductor diode lasers as pump sources for solid-state lasers was demonstrated as early as 1964.1 In the past few years the dramatic increase in output power of diode lasers 2 has made pumping of solid-state lasers practical. Recently it was shown that diode-laser-pumped Nd:YAG lasers offer advantages over lamp-pumped lasers, including high efficiency3 and good frequency stabilit...
