Diode Pumped, Passively Q-switched, Amplified Microchip Laser
Production of high energy, high repetition rate pulses is usually achieved by combining one oscillator and one amplifier in a complex and complicated system. Such a system requires active modulation with high speed electronics for short pulse production from the oscillator plus injection and synchronization of the pulses inside the amplifier. The DualChip NanoLaser is an entirely passive laser system designed for short pulse generation and amplification. The oscillator directly produces micro-Joule pulses at the desired repetition rate that are amplified in a non-synchronized two pass amplifier.

Simple Yet Efficient UV Laser
The DualChip NanoLaser incorporates the innovative passively Q-switched NanoLaser cavity consisting of a thin layer of Cr⁴⁺ doped YAG saturable absorber embedded monolithically in the Nd:YAG laser medium with two mirrors deposited at the ends. When pumped with a continuous wave diode laser, this cavity emits a high repetition rate, high peak power beam, without the costly and complicated use of electronics required for traditional Q-switched lasers. This beam passes twice, without any electronic synchronization, through a compact, diode pumped, Nd:YVO₄ amplifier selected for its high gain and ability to sustain high repetition rate. The output of the amplifier is a high repetition rate (tens of kHz) train of sub-nanosecond pulses with tens of kWatts of peak power. Since the conversion efficiency to generate green and UV wavelengths increases with the square of the incoming IR beam power, green and UV output can be efficiently generated from a passively Q-switched laser with high peak power. This efficiency allows us to place the non-linear crystals outside the cavity, in a single pass configuration, giving the DualChip NanoLaser stability and good beam quality, yet with a simple, efficient and compact design.

Compact Industrial Laser
The DualChip NanoLaser is designed as an OEM product to work in different and changing environments. Several TECs maintain the main laser components at an optimal temperature and a built-in air-cooled heatsink allows the laser head to work as a stand-alone unit. A rugged mechanical design and a hermetically sealed laser head protect the optical components from dust, fumes, condensation and vibration. These features bring an inherent stability to the laser, eliminating the need for complex and costly electronic feedback loops. A new OEM power supply has no external adjustment and allows stable operation of the laser The compact package includes an AC/DC converter to operate directly from the wall plug voltage, and diode protection circuits to protect against ESD and overheating. Whether used in an OEM system or in a scientific environment the DualChip NanoLaser is an easy to use, hands-off laser.

Many Applications
The DualChip NanoLaser is an excellent general purpose laser for scientific laboratories with the built-in simplicity and ruggedness of an industrial laser. However, it is in OEM applications that it will demonstrate its full potential as a dependable work horse, replacing complex, expensive or obsolete technologies in photo-chemistry, photo-polymerization, laser induced fluorescence, laser ablation, material processing, high speed laser marking, and analytical instrumentation.
