用两个自饱和吸收体,弛豫时间不一样的,再加上短腔设计,合适的参数,就可以产生1ns输出

频率呢?平均功率呢?

Wedge DPSSL

High Peak Power Diode Pumped Solid State Laser
All solid state design
Patented Polarization-Switching Technology
Less than 1.5 ns pulse duration
Up to 1 MW peak power
Low heat waste,air cooling

WEDGE emits pulses of 1.5 mJ energy at 1064 nm, duration shorter than 1.5 ns and peak powers exceeding 1 MW.
Based on a proprietary electrooptic Q-switching technology,this monolithic laser source features a very high peak power with excellent wall plug efficiency.

The sealed miniaturized laser head is insensitive to vibrations and harsh environments. High output peak power with relatively low Q-switch energy allows efficient nonlinear harmonic or parametric generation as well as interaction with a wide range of materials.

Harmonic options available:

Second harmonic @ 532 nm
Third harmonic @ 355 nm
Two mechanical configurations available:

Single Unit.
Dual Unit. A Resonator Unit is linked to a Pumping Unit via a fiber optic cable and a Q-switch cable.
Both the versions have built-in finned heat exchangers for air cooling.

Applications
Nonlinear spectroscopy
2nd and 3rd harmonic generation
Visible to IR OPO pumping
Material processing
Surface and intra-volume glass marking

如果为了达到1ns的脉宽,却使得频率不能连续调节就没有什么意义了

但有的用户就是需要窄脉宽,其他的不要求。
另外还有需要激光脉宽1~30ns连续可调的,不知各位有何高见?
