- “The Advantages and Disadvantages of Passive vs Active Q-Switching“
Microchip Lasers are alignment-free, diode-pumped solid-state (DPSS) lasers with a monolithic resonator, where the laser crystal is diffusion-bonded with the end mirrors, allowing for rugged, compact laser modules.
Microchip lasers (sometimes called micro lasers or microlasers) are a specific subset of q-switched DPSS lasers. These lasers utilize a passive q-switch, monolithically bonded to the laser crystal. These passive q-switches, which are typically semiconductor saturable absorber mirrors (SESAM), act as both the q-switch and the output coupler allowing for extremely small optical cavities. Furthermore, the compact and alignment-free nature of the microchip laser design allows them to be made utilizing telecom production techniques which allow for compact, ruggedized packaging at a relatively low cost. As a result, microchip lasers are ideal for integration into range finding, scribing, and marking systems, for example. Additionally, through the use of second, third, and fourth harmonic generation they can emit wavelengths from the ultraviolet @ 236.5nm through the infrared @ 1064nm. OEM fiber laser packages and modules are available.
RPMC Lasers provides a selection of microchip laser configurations to match your application requirements. These ultra-compact, passively q-switched, single longitudinal mode (SLM), narrow linewidth, DPSS lasers feature pulse durations from 400 ps to 2 ns, energy levels up to 100 µJ, and repetition rates up to 100 kHz. In addition to the fundamental 1064 nm wavelength and its harmonics (532, 355 and 266 nm), we also deliver units emitting at 946 and 473 nm.
