We report on a new method for fast amplitude modulation of blue 429-nm radiation that is produced by frequency doubling of a GaAlAs diode laser in a monolithic KNbO3 resonator. The diode-laser frequency was locked to the resonator by use of the Pound

We report 13% second-harmonic conversion efficiency of a 15-mW, cw, diode-laser-pumped Nd:YAG oscillator. 2 mW of single-axial-mode 532-mm radiation was generated by externally resonant second-harmonic generation in a monolithic MgO:LiNbO(3) nonlinea

A coherent laser radar system operating at the 1.06 micron Nd:YAG laser wavelength has been built and operated. A laser-diode-pumped monolithic ring laser served as the master oscillator. A single flash-lamp-pumped zigzag slab amplified the oscillato

A flash-lamp-pumped slab Nd:YAG laser amplifier with 62 dB of gain is demonstrated. The amplifier remains linear for energy extraction up to 12 mJ, and the beam spatial quality remains good at repetition rates up to 10 Hz. The slab geometry provides

A very high-power AlGaAs single-quantum-well graded-index separate confinement heterostructure (GRINSCH) ridge laser operating in a diffraction-limited fundamental transverse mode up to 360 mW at a wavelength of 856 nm is presented. The maximum power

Frequency doubling of diode laser radiation was achieved by operating an AR‐coated diode laser in an extended laser cavity which contained a monolithic potassium niobate frequency doubling resonator as an intracavity element. Extended cavity operat

A blue output power of 1.2 mW at 425 nm was generated using a periodically poled KTP waveguide for frequency doubling of a grating tuned, extended‐cavity laser containing an antireflection‐coated GaAlAs SQW‐GRINSCH laser diode as the gain eleme

Compact, efficient, diode-laser-based blue light sources are useful for many applications including optical storage and laser printing. Blue light can be generated by frequency doubling the output of reliable, high-power 860-nm lasers in potassium ni

Compact Blue-Green Lasers.
There is currently considerable research on compact blue light sources that use periodically-poled waveguides for quasi-phasematched frequency doubling of GaAlAs laser diodes.1,2 For such devices to become practical, they must be configured in such a

Compact Blue-Green Lasers.
Single-mode infrared diode lasers produce high output powers with long lifetimes, 1,2 and nonlinear optical processes can be used to convert the output of these sources to the blue. For instance, 430–nm light can be generated by frequency doubling
