Tunable blue laser based on intracavity frequency doubling

Apr 15, 2002 · The concept is based on intracavity frequency doubling in an external resonator geometry with spatial separation of the spectral components. The use of a fan-structured periodically poled LiTaO(3) crystal permits tuning of both the fundamental and the second harmonic simultaneously with one aperture.

Frequency Doubling – RP Photonics

Many blue laser systems are based on a frequency-doubled laser in the 0.9-μm region (e.g. 914 nm from Nd:YVO 4). By further frequency doubling (or by sum frequency generation) still shorter wavelengths in the ultraviolet region (→ ultraviolet lasers) become accessible.

Efficient cw high-power frequency doubling in periodically

A cw source of 423 nm light is presented. It is based on frequency doubling of the 846 nm output of a single-frequency Ti:Sapphire laser in periodically poled KTP. The doubling crystal is placed in a resonant enhancement cavity and is designed for first-order type I quasi-phase matching.

For example, one DBR laser in the range 930-940 nm can be frequency-doubled to the blue and the other laser having a frequency in the range of 1050-1080 nm can be frequency-doubled to the green. This can be done with a Nd doped double clad fiber amplifier.

Tunable frequency-doubled Yb:YAG microchip lasers

Next, we tried to generate tunable green light by using intracavity frequency-doubling scheme as shown in Fig. 1. Fig. 4 presented the output characteristics of the green light. We obtained a maximum green power of 520 mW at 526 nm with 6.3 W of absorbed pump power.

Encyclopedia of Laser Physics and Technology – tunable

Even though the cost for a tunable laser is higher, its use can be economical as a single spare laser can work on any transmission channel where it is needed. As the cost of tunable lasers is no longer much higher than for non-tunable ones, tunable lasers are now often even used throughout.
