Abstract

Nowadays, single-frequency diode-pumped solid-state lasers play an important role in laser frequency standard and length metrology. In this paper, the longitudinal modes oscillation of three different low-cost microchips Nd:YVO4/KTP green lasers have been investigated. A short-cavity Nd:YVO 4 laser is used to explore Single Longitudinal Mode (SLM) without inserting any optical elements inside the cavity. The experiment confirms that SLM can occur by controlling the diode pumping current and laser crystal temperature at a wide range from (300 mA to 388 mA) and (18.5°C to 30°C), respectively.
