We experimentally demonstrate an ultrafast mode-locker based on a CoSb3 skutterudite topological insulator for femtosecond mode-locking of a fiber laser. The mode-locker was implemented on a side-...
1. 意向锁https://dev.mysql.com/doc/refman/5.7/en/innodb-locking.html#innodb-insert-intention-locks官方文档,意向锁是Innodb为了支持多种粒度锁(表锁+行锁)设计的。举例:一个表 tab1id, name2, "xxxx"id是...
We present a high-precision optical phase-locking based on wideband acousto-optical frequency shifting. Increasing the modulating bandwidth stabilizes the loop at a high loop gain, thus improving ...
An all-fiber acousto-optic modulator (AOM), which features a compact structure and a low-driving voltage, is experimentally demonstrated for the active mode-locking of a fiber laser. The proposed AOM ...
As a novel practical method to realize single-polarization operation of fiber distributed Bragg reflector (DBR) laser, we proposed self-injection locking (SIL) with an active fiber ring feedback ...
Based on the closed-loop frequency locking technique, the wide dynamic range is obtained, while the linearity is guaranteed. The experiment’s results show that the dynamic range is 480 deg ∕s with ...
Spring Data JPA锁定示例项目 关于 通过使用批注测试OptimisticLock和PessimisticLocking的Spring Data JPA示例。 经过Oracle 12数据库测试 技术堆栈: Java 1.8+ Maven 3.6+ Spring Boot 2.4.2.RELEASE ...
We demonstrate a frequency locking method using the fluorescence spectrum of an Yb atomic beam as a frequency reference. For unresolved fluorescence peaks, we make the spectrum of the even isotopes ...
使用这个库! 为什么? 我经常看到的一个常见竞争条件是问题。 它是在检查和使用资源在不同的步骤中完成时创建的,另一个进程可能会在检查和使用之间更改资源。 例如:您有一个购物篮系统,其中一个客户可能只有...
High-power ultrafast fiber lasers operating at the 2 μm wavelength are extremely ... With the newly developed LC SGTS fiber as the gain fiber, high-power mode-locking was realized. By using a se
The pump laser cavity could be realigned in order to achieve total mode-locking of the longitudinal and transverse TEM00 and TEM01 electromagnetic modes. This led to spatial oscillations of the ...

When an optical resonator is close to the FDC, transverse-mode-locking (TML) takes place with drastic changes of laser mode. We report for the first time, to the best of our knowledge, the multi-...
We experimentally demonstrate a femtosecond optical parametric oscillator (OPO) synchronously pumped by a home-made solid-state mode-locking Yb:YCOB laser, which is capable of laser pulse as short as ...
今天为了研究生工作需要,一直在找PLV的代码。因为有的代码很难用,在这里分享一下我找到的相对好用的代码。 代码地址如下: ... 代码如下: ...function [ plv ] = PLV( phase_...% Compute the Phase Locking Value be
