The Laravel `isset` blade directive is used to check if a given variable exists and is not null in a Blade view.

Here's an example of how to use it:

```php
@if(isset($user))
 Welcome back, {{ $user->name }}!
@else
 Please log in to continue.
@endif
```

Conditional directives in Blade are used to conditionally display content in a Laravel view based on a given condition. These directives allow you to write clean and easy-to-read code for conditional logic in your templates.

Blade provides several conditional directives such as `@if`, `@else`, `@elseif`, `@isset`, `@empty`, `@unless`, and `@switch` which can be used to conditionally render content. You can also combine these directives with loops and other directives to create more complex conditions.

The "unless" blade directive in Laravel is used to conditionally display content based on the opposite of a given condition. It allows you to output content only when a condition evaluates to false.

Here is an example:

```php
@unless ($user->isAdmin())
 You are not an admin.
@endunless
`````
