PROJECT TITLE :
Diode-Pumped Nd:YAP Intracavity Optical Parametric Oscillator Emitting at 1603 nm: Influence of Energy-Transfer Upconversion
A diode-end-pumped actively $Q$-switched Nd:YAP laser at 1080 nm is originally designed to intracavity pump a Potassium Titanyl Phosphate KTiOPO4 (KTP)-based mostly optical parametric oscillator for obtaining the signal wavelength at 1603 nm. Under an absorbed pump power worth of eleven W, the most average output power at the eye-safe radiation is efficiently generated to be one.eleven W at a pulse repetition rate of ten kHz. At a pulse repetition rate of 5 kHz, the shortest pulse duration, the biggest pulse energy, and the very best peak power are found to be 2.4 ns, one hundred ninety $mutextJ$, and sixty seven.3 kW, respectively. Additionally, the influence of energy-transfer upconversion result on the aptitude of power scaling of the developed Nd:YAP elementary laser is experimentally investigated and theoretically analyzed.
