Novel method for pulse control in Nd:YVO4/Cr4+:YAG passively Q-switched microchip laser

The paper demonstrated that the Nd:YVO
₄
/Cr
⁴⁺
:YAG passively Q-switched microchip laser properties depends strongly on the temperature of the active medium. Up to 48 times peak power enhancement was realized by 14°C temperature elevation. This result could find a strong interest in many applications which requires new tunable compact laser sources, with the possibility to manage the pulse energy, the pulse width and the repetition rate.
