The basis of our Q-Laser series is represented in the DSS1064-Q model series. Like all DPSS (diode pumped solid-state) lasers of the CryLaS products based on resonator microchip technology, this laser is passively Q-switched. Due to the missing frequency conversion stages – and thus the missing non-linear optics within the laser – the package of the DSS1064-Q is particularly compact and can still be combined with a wide range of options (such as fiber coupling, attenuator or synchronization module). The diode-pumped microchip, consisting of a resonator (neodymium:YAG) and a saturable absorber (chromium:YAG), is used to generate emission for this type of laser. After being pumped by the built-in 808 nm laser diode, comparatively high-energy pulses with pulse durations in the range of 1 ns are released from the microchip.
Unlike CryLaS lasers at 213 nm, 266 nm, 355 nm, and 532 nm, the Q, MOPA, and High Power lasers at 1064 nm belong to the infrared spectral range (i.e., outside the range visible to humans). Infrared radiation in particular requires a high degree of protective precautions, as the waves penetrate deep into biological tissue.
This model series brings a number of advantages: Due to the missing conversion to other wavelengths follows a high degree of energy throughput of this laser. In addition, infrared radiation is strongly absorbed by metals, making the corresponding lasers ideal for ablation applications on metals. This type of laser is also used in analytics, for example in laser-induced breakdown spectroscopy LIBS. The plasmas created during ionization also release a broad spectrum of ultrasonic waves, which in turn qualifies the laser for acousto-optic applications.
