Abstract
In use of saturable Cr(4+):YAG crystals, we have demonstrated the stable Q-switched and mode-locked (QML) operation of the Nd:LuVO(4) laser. The operation range of QML in use of the Cr(4+):YAG is larger than that use of SESAM and NLM. The obtained shape of Q-switched envelope, repetition rate and pulse energy are demonstrated to depend on the initial transmittance of the Cr(4+):YAG and reflectivity of the output coupler. Using R = 60% and T(0) = 40%, the highest pulse energy of 77 microJ of each Q-switched envelope, and the highest peak power about 200 kW of Q-switched mode-locked pulses can be obtained at 15 W pump power. It demonstrate the superior characteristic of the Nd:LuVO(4) crystal.
Highlights
High-peak power and short-pulse lasers are continuously interested in laser physicist because they have various practical applications
The Q-switched and mode-locked (QML) state can only be observed as the pump powers increased from 1.7 W to 2.6 W for semiconductor saturable absorber mirror (SESAM) [1] and 2 W to 2.3W for nonlinear mirror (NLM) [2]
The operation range of QML in use of the Cr4+:YAG is larger than that use of SESAM and NLM
Summary
High-peak power and short-pulse lasers are continuously interested in laser physicist because they have various practical applications. Continuous wave mode-locking (CWML) is widely used technique in generating ultra short optical pulses. Its repetition rate is restricted by the cavity length and is in tens of MHz. its repetition rate is restricted by the cavity length and is in tens of MHz Due to these characteristics, the CW-ML pulses have various advantages such as such as wavelength conversion, supercontinuum generation [1], optical communication, optical switching, optical clocking, and nonlinear optical measurement. High repletion rate pulses will accumulate heat in materials, leading to thermal lensing in optical nonlinearity measurements such as Z scan measurement. The Q-switched can generate lower repletion rates and higher pulse energies output. The generated Q-switched pulsewidth is comparative longer relative to the CW-ML pulses so that they have lower peak powers
